This is awesome I've been telling Twitter to be aware of who they follow, now it's a practical solution I can throw at them.
Assuming that, I'll tell them to open their following list, unfollow some of the group they're already following a lot, and follow more from Twiverse and its categories, or if the category isn't there, follow intentionally themselves.
it'll balance it up. That's the route I went and now I have a relatively good mix. I can iterate again, and do that again, but this time using Twiverse.
