"More importantly, the retweet buttons will begin supporting URL shortening service other than bit.ly, and will include an option for sites to choose their own custom short URL. (For instance, we use http://tcrn.ch). Tweetmeme will also offer analytics for site owners to see how their retweets are spreading. Basic data will be free, and Tweetmeme will likely charge for more detailed analyticss. All of this, of course, also turns into valuable data for Tweetmeme to determine the most popular links and stories on Twitter, and makes Tweetmeme itself a better news aggregation site." - JohnDu™
