It might be love at first sight, but I am digging formulists.
Other than my love affair with Hootsuite, there are few other platforms I use with Twitter.
I have found the tools provided by formulists to be fantastic after only a few days of use.
They have self-generating lists for:
people who are like you, people like another Twitter-user, mutual friends, followers, people who have unfollowed, people you interact with on Twitter via retweet, or you can generate your own.
Durn, I am sure other platforms are performing such functions, but this has been a GREAT organizer for different feeds I want to follow on Twitter.
