I'm not quite sure I have much to say that will be useful; the F2F impression has kind of overwritten what was there previously. And correspondence bias all but guarantees that I will be wrong in attributing to you some character traits that were only a result of the specific situation we met in. But here goes anyway.
Online, you came across as fairly pleasant but at times edgy, generally cocky (i.e. confident but sometimes excessively so), perhaps a bit elitist in your interests, close-minded at times. In person you seemed a lot more relaxed and smiling than I'd have predicted, more curious too.
Augh, this is difficult. My mouse has hovered over the "Comment" button for like five minutes now.
In person you came across as... more muted, or more meek, than your online persona. Your emotions and interests didn't really shine through you in personal interaction, though I know they're there because I know you online.
Most people need feedback in many areas. Most people can give feedback in many areas. But for some reason I don't see a lot of actual honest feedback happening, neither in my personal life, nor at work, nor here on LW. This looks like some sort of market failure, or perhaps a bug in society.
Would we benefit from a norm that encouraged asking for feedback or critique in any area, perhaps using open threads set up specially for that? I think we would. What do you think?
