Resonancers – The Most Resonant Tweeps
http://resonancers.com/

The goals of both Tweet algorithms seem to be the same; to determine which tweets generate more buzz. That’s why they decided to compute the Resonancers Ranking based on the number of times a user’s tweets are retweeted or favorited by one of the Toptweets accounts for each language:

@toptweets (English)
@toptweets_es (Spanish)
@toptweets_it (Italian)
@toptweets_de (German)
@toptweets_fr (French)
@toptweets_ja (Japanese)

Besides the ranking to determine the most influential tweeps through the resonance criteria, Resonancers.com lets you know which of your tweets have been retweeted or marked as favorite by one of the Toptweets accounts. You should know that the tweets marked as favorite by one of these Toptweets Accounts will appear on Twitter’s Homepage for the corresponding language. You can also opt-in to receive notifications whenever one of your tweets is featured on Twitter’s Homepage. Twitter doesn’t usually send notifications if you receive native retweets or if one of your tweets is marked as favorite, so this is a great way to know in real time which of your tweets resonate and to share it with your friends.
