Thanks to _you_ for sharing Ben!
This whole new experience of knowing someone thru his blog (almost like talking to his ghost.. or temporal forks of him) was precisely what I was getting at, quite grandiosely, with my blogbeing post… to me blogs are a new state of being. And yup, DHH makes for one very interesting ghost.
As for closing old comment threads, I think it sucks BIG time, showing a silly bias for recency and needlessly marginalizing old posts, but I don’t think the email form is a good solution either. My proposed solution would be to keep comment threads forever *and* put a recent-comments module somewhere (thereby allowing people to notice these comments).
