The mention of the fact that the higher-karma, "ingroup" members of HN seem more likely to communicate with each other on twitter and in private emails than the rest of the population reminded me of bad situations I had seen on other forums.
I then thought how glad I was that here on HN it seems to happen on twitter which is still largely public. You commented quickly here about private conversations regarding HN with other high-karma members. It is reassuring that you were open, and happy to be open about this.
This gives me faith in what I find to be an excellent community that the inevitable psychological group-dynamics type phenomena are playing themselves out here in a relatively benign way, due to its high calibre membership. Your later comment "I'm too high drama for that" came across as an amusingly wry confirmation that you feel the same way.
As I said, this put me in mind of situations I have seen in lesser communities where this dynamic had led to ugly scenes. I posted about them. I then felt bad that you or someone else might misinterpret this as an accusation against them. Thats why I added my parenthetical note. Perhaps I should have reconsidered the whole thing.
