Well, this blog feature will keep track of those guests, members and followers who post lots of comments here, and display their usernames prominently in a list.
The purpose is to act as kind of a "thank you" to my commenters, since your name appearing in the list will act as a link (or "backlink") to your own profile, blog or website (if you've set it up that way). More comments for me = more traffic for your own blog/sites!
It also should help me single out those active folks who are giving lots of feedback for any "VIP" special events or "instant prizes" I might plan in the future (hint, hint!).
Please note, however, that the widget only tracks recent comments, thus will count the "top commenters" as the twelve people commenting the most, recently (i.e. if you post twenty comments today, you'll "beat" someone who posted thirty comments over six months). This is something I'm trying to fix, but I can't promise... so comment often!
