J’s Notes

Peter Kafka notes that social networking sites are having a bit of trouble keeping folks around:

comScore has provided BusinessWeek’s Spencer Ante with user engagement numbers — time spent on each site, per month, per visitor — for a slew of social networks over the past year. The data looks particularly grim for News Corp.’s MySpace, which saw time spent on the site drop 24% from December 2006 to December 2007. But Spencer notes that all the social nets are either dropping or slowing.

It looks like MySpace’s loss is Facebook’s gain, though.  While it’s not an even tilt, as more and more competitors emerge, MySpace’s hold on users is going to dwindle.
