I would like to see some analysis of which users are posting those urls.

A few months ago I did a cursory analysis of all techcrunch links submitted to HN and found that 40% of the links were submitted by the same 6 people - who submitted very little else.

Making me wonder if TC hires interns to submit their urls to places like HN - which from their point of view would make good business sense. But is ultimately bad for HN.
