So two things. First, it seems a number of users are confused by the two-stage signup process... you might want to make it clear that once you've submitted the first form, you're signed up for the mails, and don't have to submit the second if you don't (yet) want to advertise something.

Second, while I'm likely to tweet interesting links if they actually are interesting, it'd be cool if you could somehow verify and pay like .0001 per tweet in an automated way, heh.

Just a suggestion, I'm very new to BTC but I'm very interested in seeing more people and value join the economy, as that is an absolute necessity for better stability.
