I'm an iOS developer, and keep in mind when you read this that there is an entire industry of developers whose business plan is to submit pointless novelty/spam games and apps to the App Store as fast as humanly possible. Because of this, Apple has made it so you can't submit any app that simply aggregates web content or has limited functionality, and I think it's good for the App Store to impose this. On the iOS forums I follow, people get rejected constantly for simple aggregator apps like this.
So being a bit of a collector of these spam apps and having seen a lot of them, I don't really blame Apple for not being able to tell the different between those spam apps and this -- which maybe deserves a bit more consideration than the average spam aggregator app. I blame the app spammers who have wrecked the system, not Apple.
And anyway, geez, just make the project a webpage and twitter account and it has the same effect and you aren't limited to iOS. Oh, but then it's not as "cool" because it's not an iPhone app!
