Two more interesting pipes for Twitter users

I was going to put together a selec­tion of pipes (Yahoo Pipes, Yahoo’s tool for remix­ing feeds) of inter­est to Twitter users, but I acci­den­tally closed the tab with the almost fin­ished post. So I’m writ­ing about just two of them; you can look for the rest yourselves.

There are also pipes there sim­i­lar to mine, but more advanced ones.

Local Twitterstars can find the most pop­u­lar Twitter users (by number of fol­low­ers) within a given radius of a city. I’m not sure it does this entirely cor­rectly, though.

Prefriendly Friends: this one can tell you which of the people you follow haven’t fol­lowed you back. Yes, it’s that nasty :) Its author, toonerstan, by the way, has quite a few sim­i­lar pipes that can work with your followers.
