I just read about IndieKarma and installed it on my site. It's very cool. If you enjoy this site, please consider signing up. It's a no-obligation scheme. If you sign up, you get a dollar added to your account for free, then when you visit sites like mine (or Les'), it automatically gives $0.01 to that person. It's a micropayments scheme to support bloggers. 
Although I'm no fan of the design of the bar which appears on the site, the owners of the service have stated that they will make it less obtrusive and more customisable soon. As a distinctly "un-2.0" blog in design, I have some better ideas on how this could work.
It would also be useful if the user could customise how much they pay and how often. Currently, you pay once an hour, but it would be useful if you could switch it for different sites. The user should be in charge of how much they are making in micropayment.
There's more discussion over at Mashable, Fleen, Nate Ritter, Ming the Mechanic and revjim (all of whom are IndieKarma users).
