What’s the meaning of TOP 5K?
…I’ve seen tweets with a lower number of retweets than others on that list, so how does a tweet make it to this list?
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. Top Links 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.
