First Reaction to Google Buzz

My first reaction to Google Buzz:

Ok, so it integrates with Gmail. Did it ever occur to anyone at Google that it might just expose a lot of e-mail addresses to spammers? And that not everyone you follow on places like Twitter (or that want to follow you) on Twitter are people that you want to have your e-mail?

Or that people that you MUST exchange e-mail with aren’t necessarily people you want snooping your social network?
