Laying has always been past tense "That day I lay in bed for hours" or transitive "I lay the books down". Chickens also could be laying in bed, if eggs are coming out of them. Lying has always been intransitive "I was lying in bed". But nowadays, "I was laying in bed" is almost all I see.

Single quotes, not double quotes, should be used in your comment since you are not completely and directly quoting your source.
You should not be capitalising the first letter of a quote when it occurs after the beginning of a sentence.
These are just some of the grammatical errors you've made in two paragraphs. I've probably made some too. It's pointless to discuss these things outside academic contexts as long as the text can still be understood.
It is commonplace to put punctuation outside the quotation marks when the punctuation itself is not being quoted.
And they're not even that uncommon on the Internet and amongst tech people. (See the Jargon file[1], for example.)
But I get your point: pedantry is often needless, and sometimes even lacks proper justification (see taejo's comment). But it's difficult to stop seeing errors when you see them, so I would forgive the parent for being that Hacker News guy.
There's nothing to forgive. My comment was instruction on being a better reader/listener.
Focus on the things people are saying and not nitpicking their delivery and you will absorb more information.
I agree. Form is not so important.
We could talk about should. As a starting point, it would seem to me most useful to preserve meaningful distinctions which convey information, and otherwise make language as fluid and relaxed as possible. But I'm not expert.
