Hi,
I have quite a bit of experience using the Twitter API. I created a program that analyzed user relationships based on retweets for university, and I have two recent twitter related projects here if you take a look at my reviews. I am not home right now, but if you are interested, I could forward you some examples from those projects later tonight. What you are asking for is actually not too difficult, so I should be able to finish something for you pretty quickly.
One thing, the crowdreel site seems to be down right now. Could you describe a little bit more about how it is different from the openbook site?
Thanks,
Charlie Schwabacher
