What are “Community Wiki” posts?
I'm relatively new to SO, and I learned quickly that subjective topics like "what is your favorite language" are subjective and argumentative and should go in the community wiki. I wanted to get input on what people thought were some cool or useful Java classes, but the topic was closed on the grounds that it was argumentative and subjective. Doesn't this go against the whole idea of the community wiki(people asking fun or educational questions with no definite answer)?
If you feel wronged like I do, vote to reopen the question. If not, please explain why my question would be closed.
