I dig the "like" feature, if I understand the way I THINK it's intended for. We have a database system at my employer, Knowledge Base, that works as a wiki for work-related topics. Employees can go in and create articles on any work topic, process, ect. The "like" button is used to promote an article that you think has value. The more likes an article gets, the more likely it will show up at the top of the page when you search for a topic. So, let's say someone creates an article here on the boards outlining the differences in the various printings of TMNT #1, and the community feels the post is fantastic. It gets a lot of likes, so if someone comes on the forum and searches for "differences printings TMNT 1" it would show near the top. Conversely, if someone makes a post that has some bad info, and no one likes it, it's less likely to show up in searches.
