Today’s WSJ has an article about keeping track of all of your friends’ activities on different social networking sites: Social Services: Lots of sites let you keep track of your friends. The problem now is keeping track of all the ways to keep track.

I was kind of surprised by the article: basically this space of social aggregators hasn’t changed much in the past 12 months. Spokeo is the most viable option and it has been running for at least a year. But have you heard of it before? The problem of keeping track of your friends’, family’s, and colleagues’ activities keeps getting more and more complicated with everyone now joining multiple sites. (”Did you post your status on Facebook or Twitter?” “I looked for that picture you mentioned…. is it on your blog or flickr?”)

Maybe the reason a single browser aggregator isn’t dominating this space is that people are pushing updates to other applications, either mobile or RSS readers. That’s at least my solution. Or just not keep track :).
