I'm very conscious of the fact that to some people twitter is highly attractive and somewhat addictive whereas to others (including myself) it doesn't seem to appeal at all; or rather, I have a nagging feeling that maybe I should try to like it because it might be good for me in the same way that giving more presentations at work might be good for me. I guess I suspect that it is correlated with some quite important structure in human personality space.
