Twitter Explodes (isn't anyone bored yet?) by Chris Trayhorn, Publisher of mThink Blue Book, April 5, 2009 Comscore released their latest traffic figures for Twitter this week showing a remarkable increase in the first two months of this year from 6 million unique visitors worldwide at the end of December to over 10 million by the end of February. U.S. growth has been equally insane, up by over 1,000% from 12 months ago to over 4 million visitors. And we don’t even know what happened in March yet. I suspect it’s going to be huge.
