New service Plurk Karma Trends tracks average karma scores for a cross section of Plurk users, as well as providing a graphing tool so individual karma scores can be tracked.

The service comes from Ryan Lim, a Nebraska based developer (not much else was available on the service).

Users can visit the site and browse the data, or if you would like your karma scores to be tracked, add the account karma_trends to your friend list. Scores are tracked automatically the next time the karma scores are retrieved.
