This is an example of a functional cultural trait -- question and answer style should not be larded up with irrelevant pleasantries and redundant signatures that waste time for everyone reading the question thereafter. They took the time to fix it for you and you should have assimilated.
This is different from closing your question and depriving you of an answer or making you feel dumb. It's just teaching you how to communicate professionally.
I put my name on my professional communications.
It depends on the medium - SO is closer to a wiki of questions, and Wikipedia has similar rules against pleasantries or signatures on article pages. (They do allow it on "talk" pages, and SO similarly has less restrictive rules in places other than their primary questions and answers.)
Communicating professionally and coming across as polite are not mutually exclusive.
Stackoverflow was not the K&R.
