There are so many apps out there to figure out one's ranking on Twitter. There is Twitter Grader (http://twitter.grader.com/), Twitterank (http://twitterank.com/) just to name the ones that I am familar with. As a person who works with numbers and statistics everyday, I have been wondering what is the algorithm they have to rank people.
If I were to create some form of ranking metrics for twitter, I would factor in ratio of followers versus followees. But I would give more weight to the number of updates. I have seen there are several people who follow many people, and many people follow them, but have a handful of updates. They are, obviously, not engaged with the platform or they have nothing interesting to say, probably. This formula might be effective in weeding out a lot of noise in the ranking system. For all you know, the current apps use similar formulas for coming up with their rankings.
If we would like to make it more accurate, we can ask other twitter users to give a thumbs up or a thumbs down to other users. This would help us in qualitatively ranking updates.
