English was not my first language, and this peculiar phrasing confused me. Asking for clarity seems like a natural thing to do in this situation.
And as mentioned elsewhere, the entire thread seems like a good natured discussion: perhaps it felt different without the original "edit".
There is a rudeness in making it one of these faux-questions filled with implications instead of clearly stating what it is you want to say.
This sub-thread reminds me that there are many informal rules in languages that are rarely taught, and which can trip up non-native speakers. Informal shorthands, idioms, slang, etc.
1. is sincerely asking a question
2. accidentally hit they question mark key instead of the period
3. is mimicking the valley girl inflection
It's not that much of a problem here, but it's much more pronounced in places where people rarely use complete sentences to begin with. Such as chat rooms, etc.
:-) I was thinking this but couldn't find the right phrase.
It could also be expressing uncertainty. You want to make an assertion but not 100% sure you are right. A question mark at the end expresses some self doubt and leaves it open to correction. I use '?' that way quite often.
Both of your comments can be construed as linguistic pedantry. Particularly, saying "it's confusing" rather than e.g. "I find it confusing" is pretty prescriptive - and it just sounds like you're doubling down on your first comment.
If you want to ask a question about a feature of language, it helps to add the context that you're unfamiliar with the language itself. Otherwise, most readers will assume that you're attempting to correct the user you're replying to. Commenting on people's use of language is considered quite rude in most internet communities - not least because of the number of ESL users.
shortened, becomes:
I used this process, and came up with these numbers, 140 and 250, and they are kind of close?
Why you got in trouble: people thought you were criticizing the original comment for hiding a statement to look like a question. (A common underhanded tactic to do and a common criticism - "was that a question?".)
