Just going out to the banquet at DH09, so this will be a quickie. Its been a great conference. Lots of attendees, and a good energy. The stand out thing, though, has to be the amount and detail of blogging going on (see this synposis of my paper. Hmmm, I thought I had at least two or three months to write it up - and here it is already in the blogosphere!) and the overwhelming use of twitter before, in, and after sessions (search tag #dh09. I'm @melissaterras).
Check out the feed whilst it is still rolling - at around 100+ tweets an hour. The challenge for the organisers will be how to archive this resource usefully for future reference!
