Spot Fixer is a fun tool built by Gowalla for the Street Team. On this site, you can quickly improve spots flagged by helpful Gowalla users around the world. This includes adding and correcting information, adjusting locations, and merging duplicates. There’s even a scoreboard!

Don’t know of it’s one of “the few bugs”, but it’s not playing nicely with the IE9 beta. Otherwise, I think I do prefer this to Get Satisfaction.
