Well I like it because it's free, it allows people to put forward their issues without any personal or company specifics, we don't spam, we don't care if you use your real email address, we are not building profiles - our registration form is the shortest found anywhere, spam is more or less in check even with such loose measure, we have volunteers who are awesome, we are the only community which doesn't have offline chapters or any events but this community serves over 3 Million people in a month.
