We’re giving up on TrackBack. Too much spam, not enough benefit. When I have a moment I’ll home-brew some way to link from each post to a Technorati or Feedster search for inbound links from other sites; meanwhile, while nielsenhayden.com will still send TrackBack pings to sites to whom we link, we’re no longer publishing incoming pings.
If the above paragraph barely reads as English, quickly make yourself one of these, sit down, put your feet up, and have yourself fanned by burly minions until the confusion passes. Repeat as necessary.
