More likely just the fact that I can't recall an active HN conversation which tptacek didn't post in. It's kinda easier to rack up a high karma when you have a LOT of comments to upvote. His account is also about to hit it's tenth anniversary of it's creation in about a week and a half. He actually only picks up about 78 karma a day average.
I mean, thanks, and I do try really hard not to write crap. But there are people that follow my comments here --- I know because I'll sometimes reply to an old stale comment and see my reply +1'd within minutes --- and nothing I write stays negative for long. I think I do a decent job of writing here (unfortunately, it's really the only place I write anymore), but the "reward" I get for it is clearly compounded somehow.
My apologies. I had merely been attempting to explain why said user having a massive karma score isn't suspicious or surprising. It ended up launching more conversation which wasn't really intended. It shan't happen again.
