Readwriteweb made a post about Wikipedia launching the "Wikilove" button that lets users show appreciation for each other. Apparently Wikipedia is trying to ride the wave of button popularity, what with Google launching their +1 button recently and the Facebook/Twitter buttons being featured on most websites around the Internet.
All through high school and college I was frustrated at the thought that Wikipedia was not a legitimate source of research information. Now that it's been a few years I finally see why that is. Wikipedia has strengths including a self-policing community. However, this community has taken their process to the extreme.
