About this tool
Every once in a while, I find a person who's just so knowledgeable that I say to myself "whomever he's follow has got to be just as smart. I need to follow them too!". That's what the Follow by friends is for.
Tweepi helps you analyze and filter tweeps out - the geeky way, with numbers in a table - based on their activity and sociability. We spent so much time perfecting Tweepi that now you can also sort and search (filter) the results anyway you like on per page basis.
Premium Tweepi users can do that for all users they follow or following them, not just for the current page, along with loads of other time saving features.
