Not a fan of Twitter at all
I'm not either as a "personal" social networking tool.
The amazing thing about twitter tho, is that it will and already is becoming the quickest most efficient way of getting your news straight from the source.
Many, many politicians, actors, athletes, writers, analysts, etc, etc all use it and update it regularly.
Just by simply going to their pages and clicking "follow" you get their up to the second posts, especially since the mobile site works extremely well on all smart phones.
