Interesting Take on Twitter

TechCrunch has a great article up about "Why Twitter Hasn't Failed," exploring why Twitter is different in terms of distribution in feeds than facebook, FriendFeed, and other sources that produce feeds to specific audiences (vs. blogs where we don't often know where they're going.)

In the political context, we can see that Twitter does have a very targeted marketing capability in this respect. Campaigns - like Obama for America - can track exactly who receives their tweets from the candidate and use it to help hone message.
