even I was inactive for a long time I am still at #272. That made my day

I don't recognise most of the members in the first few hundred. Maybe I should look around Bitcoin Talk a bit more. Also, I put nullius on ignore. I thought he was just here for a bit of ego massaging, and not for the benefit of the forum, but obviously I haven't read most of his later posts, so perhaps I misunderstood his motives.
I guess it's using statistics rather than actual viewpoints of the public. So the data is always going to be a little skewed.
