Starting Friday at midnight your Facebook homepage url can be.www.facebook.com/johnolerud instead of www.facebook.com/home.php?ref=home, but only if you claim "johnolerud" before anyone else. It's kind of like a vanity plate for your social web life. John Olerud is going to be pissed, though.
I'm sure that there are more than a few enterprising folks out there trying to figure out how to register non-trademarked company names before those companies do. Since Facebook is being used more for marketing, it might be worth it to stay up late Friday and do some e-squatting.
It was pointed out to me this morning that Google's total pre-IPO funding was $25.1 million. According to TechCrunch, Facebook has raised $716 million to date. That's not bad (it's good, in fact) but it's different and what happens when your revenue model is less obvious that that of Google.
