I'll give away one of my startups to someone on HN
https://news.ycombinator.com/item?id=675640A little over a year ago I built ronin.tehcrowd.com as a way of learning python/django.
Tehcrowd aggregates status updates for groups. Read more at tehcrowd.com/secret/. Here's an example crowd: http://ronin.tehcrowd.com/crowd/top-rubyists/. I never really launched this site because: a) Similar sites have recently launched and b) It's yet another twitter app.
I'm sure there's something cool that could be done with this project. I'd love to see tehcrowd go live. So here's the deal: Post why you should get the project and I'll give the domain and code (no strings attached) to the highest rated submission.
No trolls please.

EDIT: The neatest part of this site was my algorithm for filtering tweets. Each tweet was ranked based on several variables: user follower/following ratio, number of tweets by that user, number of "relevant" terms in the tweet, whether that user is tweeting at another member in the crowd.
I.e: A user with a high follower/following ratio and a low number of total tweets is less spammy and their tweets were ranked higher. Or if a user tweeted at another twitter user that's also in the crowd the tweet was deemded to be relevant and also ranked higher.
As more feeds were added to a crowd this filter became more strict thereby increasing the quality of the crowd.
