1. It's 2011, and I started out by seeing this:
https://plus.google.com/not-supported/?ref=/up/
I had to "lie" to Google and pretend I'm Safari. No big deal, but Google of all sites should not have these kinds of crap restrictions.
2. When I tried to log in, I was spammed that I should "link to Picasa", whatever that means, with the only options being to do it or Cancel (at which point the entire Google login is stopped!).
So far, from my point of view Google+ is making basic mistakes: I am discouraged in every way to log in.
