Good point! Cringely was talking about the disadvantages of huge social graphs recently, too (http://www.cringely.com/2010/05/lets-get-small/ http://www.cringely.com/2010/05/lets-get-small/). I don't think so. I think the interesting messages coming from the 80% I communicate 20% of the time may be even more valuable, e.g. to casually keep in touch, learn interesting stuff, etc. A social app is not just status messages.How will the Google social app easily absorb all the photos, etc. I'm sharing in FB? What if the friends I enjoy on FB decide not to join the Google thing? I think tehse are huge drawbacks. Look at Plaxo, Ning, etc. They are just wannabes in this space. You are right about MySpace and FB, but the crowds they were catering to quickly diverged. That also explains how LinkedIn can thrive independent of FB.
