Yet another app for Bitcoin has just been launched that takes advantage of a Bitcoin property that other payment processors just can't compete with: the ability to process micro-payments.
Feedzebirds pays Twitter account holders for re-tweeting advertisements, with payments as a function of the user's follower count.
As per usual with Bitcoin, no personal information is required; all you need is a Twitter account and a Bitcoin payout address. You also have the option of providing an email address to enable payouts to your BTCinch account.
Once you're signed up, all you need to do is look for tweets with the tag #FeedZeBirds and re-tweet those tweets to get paid!
If you're new to Bitcoin, but not new to Twitter, this is a great way to start earning Bitcoins.
