The folks over at BitcoinPlus have a neat little Java App that lets you generate bitcoins through your web browser. Also, you will get paid free bitcoins even if you have a slow computer and a slow connection, on a fairly regular basis.
You won't get paid a lot, though, I've been using it for two days and half about 1/2 a bitcent. Whoopeee! Given current prices of bitcoins, that's about $0.03. Not enough to retire yet, but I'm getting there... Another thing to note is that the site will only send you bitcoins in increments of 0.01 BTC, or 1 bitcent, which might take a couple days to get to. Plus, the site doesn't really make it clear upfront that there is such a limit, it's only when you actually get to the send screen that you learn that you need 0.01 to receive any bitcoins. But it seems this is a standard limit many free bitcoin services put on their payouts.
Still, a very cool and fun way to generate bitcoins for free while browsing the web. And, it looks like they may have an option for embedding their app in the future. Neat!
Alexa shows that the site had a burst of traffic when it debuted and then it has slowly tapered off, suggesting that people may not be impressed with the slow generation and don't stick around. Well, I am sticking around until I get my 0.01 BTC at least!
