Twtrfrnd finds mutual friends on Twitter

One way to figure out whether you should follow someone on Twitter is by seeing who your mutual friends. Twtrfrnd makes that very easy: just enter your username and someone else's, and it does the rest. Soon, it will even let you log in to automatically see friends you have in common with people who have recently followed you.

Finding common friends is a good way to know whether a specific person might be worth following, but anybody can follow a lot of your friends. It's not the most selective way of doing things. That's why there's also the "indicators" list. It shows you which of your friends are following someone, giving you a more accurate indicator of how interested you might be in that person's updates.
