Recently Updated

I often add updates to old posts. This page lists posts that I’ve edited after the day when they were originally posted. Each significant update is also posted to Twitter with hashtag #mjtsaiupdate and includes a direct link to the new part of the post. There is no RSS feed for updates, but you can subscribe to the Twitter search using NetNewsWire or subscribe to the #mjtsaiupdate hashtag in Feedbin or News Explorer.
