So what's up with RealID and multiple accounts?

don't give out your realid for now, until blizzard added more privacy options.

This. I have a couple of people I would love to add to this, but no way am I giving up my (full) real name and my logon email to them. I'm not sure why it was implemented in it's current format, maybe it was rushed to meet the SC2 release deadline?

They want to ensure only people who really have reason to trust each other become real id friends.

Actually, no. They want to create more opportunities to cross-sell their suite of Blizz games such as SC2, WoW and D3 to people who may only be playing one of these products. Why else are they not charging for the use of RealID?
