If you used to check my Twitter stream in the center column at the bottom of my blog, you would have noticed I have just replaced it with my Google Buzz profile stream instead. Yes, you can still see the my Twitter activity, but you will also be able to (1) see aggregated content/activity coming from other sources in one place, (2) subscribe to the stream, and (3) comment on each of the entries. As, I said, a minor update to improve its functionality a bit more.
