I've recently hit the 2k threshold for Twitter. For those that don't know, there's a mystery algorithm that limits you from following more than 2k people if you do not have enough following you. At the end of the day, it makes sense as they're really just trying to limit spammers... And no one likes a spammer.
I pinged the crew @ Twitter about this, and rec'd a canned response stating something along the lines of 'Best practice suggests a one to one ratio of following to followers....". Great, but not helpful given my situation.
So I'm now forced to go through and figure out how to un-follow some to follow others. This and bad paper cuts are two inconveniences that my life could deal without.
