A few updates: Social graph changes (follows, unfollows, blocks, and unblocks) are now immediately applied to a user stream without requiring a reconnect. For example, if the user follows a new user, and that new user subsequently tweets or initiates a social event, the tweet or event is delivered to the first user's stream.
Retweet social events are now filtered in all cases. They are redundant on User Streams as the retweet itself is always delivered. In certain cases, a direct message deletion event wasn't delivered. Now, if a direct message is deleted directly after creation, the event is always delivered to the user initiating the deletion. Ideally both parties to the direct message would be notified, but this issue will have to remain open for the time being. Look for more changes in the near future. -John Kalucki http://twitter.com/jkalucki Infrastructure, Twitter Inc.
