I'll admit it bothers me a bit. I don't have a problem with people who participate here submitting their blog posts but as a fairly active member of this community I'm a little offended by someone who doesn't contribute in any other way.

That said I don't suspect foul play here simply because someone who was using voting bots or some other form of cheating would probably do it more often (most of this guy's post never get above 1)

If you have something interesting to say, someone else will submit it.

Unless you don't already have readers from HN.
