A year ago
Everything in this post is about hypertext. It has no links....
I don't often single out a year ago notes, but this is a good one -- and one that wasn't much discussed at the time. One of the nice things about Tinderbox is that features like this are easy to build yourself, A Year Ago is actually a pair of agents; one finds all the notes written within a three or four-day window a year back, and the second selects the note that seems most substantial from the shortlist.
