Sorry, my last question is answered in one of the linked posts: you can still delete your profile, but its apparently created by default (albeit fairly empty) when you create a Google account.
Still a lot less evil and Facebook's constantly changing privacy settings, but not the standard they set themselves.
To me the big issue is Google+ results in the SERPS as opposed to other social networks. I would rather see neither.
