I'm concerned about posts like the following:
$\langle$ Problem statement appears here$\rangle$
idk - u plz hlp me?!!!
I find that sort of question to be really rude; though probably not intentionally. What might be appropriate to say in a comment? Sure, every such post could be edited by someone, as we do poor grammar in general, but that's a drain on editors' time, which would be better used to help in mathjax formatting.
Perhaps a simple line added to "How to ask a good question" (meta post) to articulate some informative consensus statement addressing this?
Similarly I suggest we should discourage use of emoticons in posts, or use of multiple exclamation marks, etc.
Any ideas? Any thoughts?
