I hate having to admit that I'm wrong, so I'm not going to. However, I will concede that I missed a very important point in my post yesterday about the gender imbalance on Foursquare. Fortunately, a number of astute reader comments drew my attention to the fact that women may be avoiding location-based networks out of concern for privacy and personal safety.

Last week brought a report from Forrester suggesting that Foursquare, a leader in location-based social networks, is disproportionately male, with a male-female ratio of nearly four-to-one. As one might expect, this excited some comment in online forums. In addition to potentially discouraging single men from joining, much of the buzz around these findings seemed to imply, in a vague buzz-y way, that the lack of ladies -- or glut of guys, I guess -- somehow bodes ill for Foursquare's future as a marketing platform.
