TopLinks are a live continuously updating collection of feeds of the top 100, 1000, and 5000 new links posted every day by influential people on Twitter. TopLinks are computed based on the number of tweets for each link and the aggregate influence of twitter users who have tweeted the link within the first 24 hours of the first tweet.
During the first 24 hours, if a link rises in popularity amongst influentials, the link may move from Top5k to Top1k to Top100. Once a link earns a Top100, 1k or 5k badge, it keeps it forever – think of it like the opening night sales for a film. If you install the Topsy Plugin for WordPress, TopLinks badges that your stories earn will be displayed alongside the stories.
Wait a minute you say – isn’t this is a real-time feed? How does Topsy know what links are TopLinks so quickly? Normally, such a list would require waiting a full 24 hours after a link is first posted. In order to provide a real-time feed, Topsy does not wait for the day to be over. Instead, Topsy generates a predictive list based on the number of tweets and the influence of those who tweeted the previous day’s top links.
TopLinks are currently shown for recent tweets from he past week, but Topsy will soon show older TopLinks as well, over the entire collection of tweeted links collected by Topsy over the past year.
