Remember how NotchUp spammed us all alst week? Get ready for a lot more. Brad Fitzpatrick, the LiveJournal founder who noisily left Six Apart for Google last summer, has launched his first big project: a tool which identifies your friends across multiple social networks, so you can invite them all wherever you go. What this means: If you're sick of zombie bites on Facebook, you're going to hate the World Wide Web after Fitzpatrick gets done with it. But forget the spam issue: Am I the only one who thinks this is a terrible idea on principle?
