Formulists is an easy-to-use web app that helps you create Twitter lists and keep them updated without hassle.
As Formulists is technically still in development, they only accept a specific number of new users every day. But with around 150 new spots to grab a day, its not that hard to create an account. Once you’re in, Formulists displays a video tutorial that explains the basic functionality and you're good to go.
The best thing about Formulists is that it lets you not only create your own custom lists from scratch, but also create them based on a series of stock lists already provided by the app. These lists take into account several criteria, such as interaction, retweets and lists you've been included in, and generate automatic lists that you never have to manually update again.
Formulists includes a bunch of options and filters to make Twitter lists fit your needs as much as possible. The app is particularly useful to find new people on Twitter, and also for those of you who follow hundreds of people. On the downside, you have to be a bit patient when creating lists, as they take a while to appear on your profile.
Formulists is a handy web app that creates self-updating Twitter lists in a few easy steps.
