How about this one, with 1419 upvotes (and hey; I'm in the list too!): http://stackoverflow.com/questions/9033/hidden-features-of-c
Or this one: http://stackoverflow.com/questions/194812/list-of-freely-ava...
Or: http://stackoverflow.com/questions/2245196/c-urban-myths
Or perhaps: http://stackoverflow.com/questions/81584/what-ide-to-use-for...

I can go on. Hell, here's an aggregated list of great questions, almost all of which are closed: http://www.quora.com/What-are-the-most-interesting-Stack-Ove...
All of those questions have a massive amount of upvotes, i.e., the community thought they were interesting, well written, and, mots importantly, useful. All closed as "off-topic" or "not constructive." Give me a break.
