Twitter continues to explode in popularity. One estimate has it growing 752% in 2008, hitting 4.3 million unique visitors in December.  It picked up more than 1 million unique visitors in December alone,and by all accounts, the growth is continuing, and possibly accelerating. I’m working on a couple of pieces about Twitter for business users,  but wanted to share some of the cool posts I came across in January–my favorites– and some useful tools.
