GoogleBuzz! Don't knock it and wait for tweaks

Buzz has good potential - integration with Google products is key. With a few tweaks it can potentially take over facebook - user profile should contain more details/personalization, the interface could be more attractive, and lack of targeted advertisement is nice. Taking over twitter is more difficult because it is a completely different platform - word limit sets it apart from facebook-like social media, making twitter more succinct and less personal, which means strangers feel comfortable tweeting to one another. However, this can be worked out easily with the option to post publicly and the option to search/follow users that are not in your Gmail contact. Overall, an interesting start!
