As a Brizzly replacement for only one Twitter account. It can send to facebook, and pull in your own FB updates, but it is not a complete FB integration yet. It is more like Friendfeed on pretty steroids, with a full Twitter and Buzz integration.

Hopefully they will fix whatever issues they have with pulling multiple Twitter accounts at some point, as well.

Speaking of Buzz, it has suddenly become useful to me again, as it is integrated with my other streams and actually easy to interact with. There seem to be a few issues with the timeliness of the Buzz feed, but it is still more attention than Buzz has received from me in months.
