There is some standardization work going on around "XMPP" - which started as an IM protocol (person-to-person), but has added extensions to support "publish-subscribe" (PubSub) and "Personal Eventing" (PEP).
I think a distributed system, more like email, may be a more sustainable way to deliver the Twitter-like services that people desire. There will still need to be centralized servers that support "tracking" - so people can subscribe to updates for groups or tags.
Unfortunately, Twitter-like functionality has N^2 scaling characteristics (since each Tweet generates a message that has to be transmitted to each follower). So any architecture designed to handle the load will have to efficiently manage the collection and then distribution of all of these messages.

This is a new "rockstar" site in my opinion. You can now tap into the global gestalt of twitters our there by searching on any keyword. It's a great way to find out if people are sharing the same issue as you (e.g, Firefox 3 crashes, services being down, etc.)
And it's FAST. I hope it doesn't get slower as it becomes more popular.
Twemes, btw, only searches hascodes in the twitter stream.

A public experiment that was better in theory than in practice: "In the end, the restrooms, installed in early 2004, had become so filthy, so overrun with drug abusers and prostitutes, that although use was free of charge, even some of the city’s most destitute people refused to step inside them."
