Wikipedia:COMMUNITY

Some people think that user categories that serve no real collaborative purpose, games, , , et cetera, need to be deleted because they are not useful when building the encyclopedia. They often cite pages such as WP:MYSPACE and WP:ENC.

Some of the rationales for keeping such pages is that, more than just an encyclopedia, . A community likes to have fun at times, and, at other times, it's 100% serious. Such pages are helpful in helping users feel better when contributing to the encyclopedia. Just because it's a page that isn't serious doesn't mean it hurts the community. In fact, it very often helps by taking away the stress.

Usually it's a bad idea to canvass, but there's actually such a thing as good canvassing when it comes to improving the site—mainly when it deals with behind-the-scenes maintenance. For example, if it weren't for one user bringing articles for creation's backlog to the attention of other members of the community who had never heard of it before (like many users before they saw a user make a post about it), the massive backlogs would never have been cleaned up.

Category-populating userboxes are one of the user-friendly ways of pulling together the huge amount of editors on the site in hopes of finding those with similar interests to help edit the lower-traffic areas of the site. Walk down any given street and it's unlikely you'll find many people interested in the Napoleonic Wars. You might even try posting a classified ad in the local newspaper in vain. However, drop by our interest category and magically, you have a huge pool of editors who are more than likely willing to help research some changes for an article on the subject.
