I am a big user of Twitter, but clearly not as big as many people, and I am proud of my 3181 followers. When I look at followers, especially people I do not know who comment on my tweets, I have devised a quick scoring system to see how creditable they are, rather than just looking at their followers.
I basically take their number of followers and divide it by the number of tweets they have written by doing some simple estimated maths. Right now, I have roughly a score of just under 1. Someone else may have a lot more followers of me, but has ten times as tweets as followers, and so their score would be 0.1. Someone who is well known may have a lot of followers and very few tweets, giving them a very high score, something I am never lightly to achieve!
This scoring system is not perfect but it helps me judge how creditable comments are, especially when they are hurtful. One day, this scoring system may catch on and be included on everyone’s twitter page, as a way of rating people!
