Tweetmeme.com is a popular service that allows users to find tweets and do retweets easily.
TweetMeme is a service which aggregates all the popular links on Twitter to determine which links are popular. TweetMeme categorises these links into Categories, Subcategories and Channels, making it easy to filter out the noise to find what you're interested in.
Using the TweetMeme Button you can discover new content and tweet about it. The button provides a fully integrated URL shortener and the title of the story or page. Each link which is posted on Twitter adds one to the tweet count for that story. Once the story has reached a critical mass of tweets, it makes it into the top 10 on the front page and gets tweeted by our Twitter account.
