I've been hesitant to try Google+. I don't want to "re-invite" all my fbook, linked in and Twitter contacts. Is there any way to easily port over all my contacts w/out pinging them again?
@Frida: yep! Google+ is actually pretty smart; it uses your email contacts to show you who all you might like to import. I don't know how well it works w/ a Google Apps email address, though.
