I've been wondering how long it would take for a meta-social networking site to emerge (or whether I should create one thereby making millions), allowing you to maintain active accounts on facebook, myspace, etc, with one single interface to read and post messages and comments, but of course Wired got there first. Sorta.
And yes, I did mean to post that many months ago! But it's still relevant because interoperability is only going to become more important in the social networking world.
This post on the Gartner "Hype Cycle for Emerging Technologies 2007" report includes the familiar Gartner Hype Cycle diagram, updated for 2007, which is more than you'll get from the Gartner site (for free, anyway).
