Just curious: it seems JustHackIt was posted first here on HN and later on on TC? So how come they write about it, as I thought they were rather strict about only writing about "first hand news"?
My understanding is that both this site's community and the TechCrunch writers view HN as a geek ghetto. Thus, putting your site up here for feedback isn't really announcing or launching it. It's more akin to demoing to friends and family to get feedback.
