One of the important things to keep in mind on a consumer site is that your users will find a way to use your site to do the things they want to do. Rather than restrict them, find outlets in your product that enable them to accomplish those things.

Dogster’s Presentation at Community Next is terrific and in it they talk about “helping users achieve their goals rather than co-opting them to further your own.” I paraphrase, but that’s the gist of it. I couldn’t agree more. The presentation is excellent and highly recommended if you believe community is important.
