Marc dropped an "emotional outburst" (his words) on the blogosphere last night, after Om Malik wrote a post on white-label social networks that didn't mention Marc's company PeopleAggregator.
The first person I ever heard say "social networks are a feature, not a product" is Paul Martino, who brought Marc in to advise Tribe Networks back when the whole world temporarily didn't care about the Internet. Marc has been thinking and building this stuff for years, and not only is he defining the white-label social network space, he's been an essential thinker for me and plenty of other entrepreneurs with his concept of "digital life aggregators" combined with vertical web services. Vertical web services like, ah, events.
Thanks, Marc. Keep leading the charge. And occasionally wearing your heart on your sleeve is way OK with me.
