This is one of those things that I really didn't put much stock into until I saw this award-winning question posted...
https://softwareengineering.stackexchange.com/questions/156673/which-editor-is-best-for-php
... and yes the question itself contains as many words as the title. It would make Yahoo! Answers proud. I am all about short, sweet and to the point but that is absolutely ridiculous that we actually allow 6 word questions to be posted.
We already have a minimum character feature for comments, so why not a minimum word feature for posting a question or answer? If you agree, what should the limit be?
