I was wondering if anyone could recommend a service that can expedite building lists on Twitter? Either drag and drop, or sorting functions, etc. I follow about 15,000 people on my personal twitter and several within that follower count are people I do know and want to read tweets from, so of course i want to add them to a separate list. The problem is that sitting there and scrolling to the start of the people I follow and manually adding each one is a BEAST, and then i tried using Twitilist and it only loads the last 1,000 people that I followed. Any recommendations of a work around to make list building easier?
