Who is Robert Scooble?

The buzz last days has been that Robert Scooble (Scobleizer – Microsoft Geek Blogger) is leaving Microsoft. It’s all over the blogosphere and seems like the biggest event ever for all bloggers. That’s why I’m so curious how it comes that I’ve never, ever hear of Robert Scooble before. Okay, ignorance is a bless, I’m aware of that – but I am following 100+ blogs every day so the chances that some of them would mention this guy can’t be that low.

Anyway, I must append some Microsoft friendly blogs to my blogroll, that’s for sure. Can anyone recommend some good blogs that I should read?
