Ged Maheux, for The Iconfactory:

When it comes to online advertising, the big question has always been: how do I get the most bang for the least bucks? If you’re a small developer with a limited budget (like we are), then you’re accustomed to carefully picking and choosing how and where to promote your product to reach the widest possible audience. We understand the struggle – which is why we created the Twitterrific Ad Network!

Now you can advertise your app, website, product or service directly on Twitterrific’s expansive network of tech-savvy users for just $100 a month. For that price we guarantee 1,000 tap-throughs – not impressions but actual visits – to your App Store page or website. What’s more, we take care of creating the ad for you ourselves and even provide App Analytics for iOS or Google Analytics for websites.

This sounds like a great idea for indie devs (great price), a tolerable idea for Twitterrific users (the app is currently funded by a tip jar; the ads look nice), and a bad idea once Twitter finds out (I don’t think I’ve ever seen a Twitter client implement their own ads).
