I feel bad for you because you couldn't handle the inanity of the Internet. You're going to need thicker skin if you want to find success, because people will always cut you down, doubly so if you're on the right track.
It sounds mean, and maybe it could be phrased nicer (minus the "I feel bad for you" part), but it's not wrong. All socially interactive sites online will eventually attract people who attack someone doing a service, as in the case of the OP, and they will do everything they can to insult you, make you feel bad, or generally fling all manner of dirt in your direction. Worse, if you stop doing what you're doing you're essentially giving them exactly what they want: Stop posting.
The best solution is to continue. Double down if need be. Learn something from it and move on. In fact, if the OP really wants to get back at them, continuing to write is probably the best way forward. Hell, find someone who would be willing to edit your work. Also, recognize that mistakes will be made. Multi-million dollar publications with dozens of editors on staff sometimes have glaring mistakes slip through the process. There isn't much more you can do as a solo writer without hitting diminishing returns in the pursuit of perfection. Judging by the comments, it looks like the "mistake" wasn't, which makes this situation even more absurd, and the willingness to give in even more so!
Ultimately, just recognize some people are toxic. And like diminoten said: They will always cut you down. If someone isn't willing to offer constructive criticism, or take the time to write it, nothing they've written is worth reading. Treat it that way.
Amusingly, I had something similar happen to me on social media recently over my use of the colloquialism "performant" that's often used here on HN (and plenty of places elsewhere--just search Wikipedia for some examples). Except in this case, it's not a word. Rather than do what they want (I'm not sure what that would be), I doubled down. They weren't adding anything to a technical discussion (and admitted they knew nothing about the subject matter), so I politely told them that if they wanted to interject with anything, to keep it on topic. They didn't. I persisted. They blocked me. Sometimes the problems solve themselves, but it's important not to let them dissuade you from enjoying what you're doing.
You HAVE to be a bit more aggressive. It's not easy (I know, trust me), but in this case, the OP is doing something that sounds like it's beneficial to a lot of people. Don't stop doing it because of one jerk. If you do, we're all worse off.
I think you (and the GP) got it wrong that what made me stop was having someone being rude to me on the internet. The lack of confidence is because I know that there were and there would be for a long time a lot of mistakes in my writing. And my blog is about writing of all things, which makes those mistakes worse. What affected my confidence was not that the commenter was rude, was that he/she was right
The comment about the word "certificated" was correct in its spirit. Even if there are arguments to say that it might a word and could be technically correct in some form, I did want to write "certified". I even edited my post.
I have noticed published mistakes myself and had private and much nicer feedback about other mistakes before. That was the confirmation that I actually do a larger number of mistakes than a native speaker.
The free blog is one of the things that I do and lacking the confidence that I could do it well enough, I decided to stop doing it and go for other things. I had several nice comments here that can make me reconsider my decision, including yours. As for GP, it was not helpful or correct, it was just arrogant and presumptuous.
The reason I say this is because, quite frankly, if you hadn't taken what was said personally, internalizing it as thus, you would still be writing and none of this conversation would have taken place. You disagree, and I understand; however, recognize that as an outsider looking in, I think you're too dismissive of the impact this interaction had on your work (you stopped writing). It doesn't matter whether the person was right or wrong: The fact they said they didn't trust you because of a single mistake was demeaning.
For what it's worth, I still stand by what I said earlier: If someone isn't willing to write constructive criticism, preferring to resort to negative language or insults, then nothing they say matters. If they're right, they're right, but the best you can do is just ignore the negative sentiments and move on. It's not easy. You'll second guess yourself (as you're doing). And you know what? That's fine! You'll be more cautious next time, and you'll have the added confidence that you can deal with similar responses in the future (I'm serious).
To put it another way: It's not so much that the individual in question was correct that dinged your confidence--it's how they said it. I'm almost certain had it been written differently you'd have thought nothing more of it; e.g. "Hey, I think you meant to write 'certified' rather than 'certificated.' Just thought I'd let you know."
Think for a moment on that. If this were written instead, would you still feel your confidence had taken a hit? I'd wager not!
Chin up, my friend. If an asshole is right about something, it doesn't make them less of an asshole--they're just an asshole who happens to be right.
> "If this were written instead, would you still feel your confidence had taken a hit? I'd wager not!"
I certainly would. Actually, I did. My confidence had already taken hits before from nicer private feedback I got before.
I also disagree that I should dismiss everything that an asshole is saying just because they're an asshole, even if they are right. I take what is right, improve my text and forget about them being an asshole.
Therefore, focus on checking that your regular readers are enjoying what you write, instead of focusing too much on actual or perceived weaknesses.
I think perspective here is important. While anything that a speaker and hearer agree has meaning can be considered a word, there is definitely a separate matter of blending in to a particular linguistic context. I wouldn't deny that.
But I do think it's important to remember that what you're doing is trying to blend in to a particular linguistic context... not trying to be right instead of wrong. In some English contexts, "kindly do the needful" is a normal, unremarkable phrase. In others, it barely registers as English at all. In some, you can rent a flat when you go on holiday. In others, it's an apartment and a vacation.
Regardless of context (to my knowledge), we talk about a "building site" not a "building place", for no apparent reason.
There are no reasonable criteria by which any of those phrasings can be considered "wrong". They just don't sound natural in some (or all) contexts. But when you consider this perspective, things get muddy quickly because language usage varies so much. Like... I would say your sentence "I have noticed published mistakes myself and had private and much nicer feedback about other mistakes before." would sound more natural with "have" added... "I have noticed published mistakes myself and have had private and much nicer feedback about other mistakes before." But I can't say a native speaker would never say it the way you did, so what do we take from that? Probably any piece of writing can be improved, whether by a native or non-native speaker. At what level do we say the speaker sounds native? It's just all very muddy.
It's not even clear who gets to count as a native speaker. Is someone who grew up speaking Indian English in school but a different language at a home a native English speaker? Their accent and word choices will make very clear they aren't a native speaker from an "English speaking country" (US, UK, Canada, Australia, New Zealand), but... English is an official language of India and spoken every day by millions of people there. Is someone who grew up in Amsterdam and learned English in school from childhood and has used it extensively as an international / business / default fallback language for their entire adult life a native English speaker?
Nothing with language is black and white. If your goal is to be understood and to have the fluency to express interesting ideas with nuance and clarity, then you're already there. Are there tells that you aren't as high up on the "native" spectrum as others? Yes. But if I applied the same critical eye to my own writing after 5 years when I've forgotten it was me who wrote it, I could probably find things I would perceive as non-native there too.
So basically I'm just trying to say... your skill in English does not in any way appear to be an impediment to using the language effectively. While there are things which could make you sound more native, those aren't a matter of right or wrong English... they're a matter of word choice / phrasing that sounds more familiar to the context you are speaking into.
