Tffratio pokes fun and tries to analyze what type of person/account you are based on the ratio between followers and whom you follow. There seems to be 4 types of people, but I won’t spoil the reading by telling you up front.
You can either go to the site and simply type your Twitter id in, no need to provide a username and password unless you are private. Or simply send them a tweet to @tffratio and it will send the reply right back!
The site itself shows some samples down the right margin and it is all in good fun. They even have a badge you can use to promote yourself to a tweet button to send the results out. I can say I fell at a 7.20 ratio, go see what it means, lol.
