This is a really trivial question, but I've seen different conventions and some edits regarding which is correct, so I'm curious:
Should question titles be title-cased or sentence-cased?
sentence casing is a lot easier to read. On this page to the right is the "Related" questions list and not many of those have
Title Casing and they are easy to read.
Not sure if it'll stay for long, but for this question title (Which is currently appearing for me) on the right hand side:
is just that much harder to read because of the title casing. Maybe harder is not the right word, but it just looks less desirable.
It's really more a question than a title -- use sentence case.
Of course, this leaves me wondering if we could call that field something better than "Title" on the "Ask Question" page. I can't think of anything better, though. :/
