I think it is somewhat presumptuous of techcrunch to consider themselves as determining what is under or over the radar, as the metaphor goes. Techcrunch has less influence that it supposes.
It may seem presumptuous, but it is undeniable techcrunch has considerable influence.
My only concern is that knowing certain important people from TC now read HN, there might be an influx of spam from people looking for attention. Especially now that everyone knows it is possible get TC coverage by posting here.
This would only be a bad thing though if the "hey look at me!" spam really got out of hand. Otherwise, I really like reading about peoples startup projects (as I'm sure Arrington and others do too), as long as the intent is genuine.
