This shows the stepwise growth of Cognitive Labs - Q4 2007 was more than 300% over Q4 2006, with about 1.5 million visitors. Q1 2006 and Q4 2006 both had number one hits on digg. With the acquisition of brain.com, we've had additional lift.
We're up to 2,319,000 users. I never thought it could get this big, and we're basically in stealth mode. However, it's likely that this is only the beginning. Where should we go from here?
