I've never been on facebook. I assume it's at facebook.com or something. Evidently, I'm the only one. facebook is now valued at $15 billion.
Now Microsoft, already a partner with facebook in advertising, is dropping $240mil on them to get an equity stake, presumed mostly to fend off Google from gobbling up this advertising cash cow and keep a foot in the Social Web 2.0 waters.
What's it mean? It seems to be a big deal, but it's a drop in the bucket to these companies, so I think Google probably has bigger fish to fry. And with Microsoft pushing their Live Spaces sites, who knows where it will lead in the future.
