I would still be able to use Gmail, but not Google Reader, which is a pain in the ass, because I'm using it a lot. (that's fucked up, if I hadn't subscribed to Google+, I'd still be able to use Reader without problems).
We’re starting to roll out verification badges on profiles so you can be sure the person you’re adding to a circle is who they claim to be.
...
For now, we’re focused on verifying public figures, celebrities, and people who have been added to a large number of Circles, but we’re working on expanding this to more folks.
get over it
You can use any name you want, as long as it is what you are commonly referred to as, either in the real world, or online (if that is your "real world") according to their TOS. As long as it has a first and last name
The only people I can see having a problem at this point are people like Emperor... and I assume you've made a decision on all of this by this point?
Not apparently true - although Lady Gaga and 50 Cent use a first name last name approach, so did I ("The" being the first name) and so have Kaliya Identity Woman, Doctor Popular, Bug Girl and Rainyday Superstar. Google seem to want you to put you legal name in the name field (or a reasonably close approximation, that you can see is derived from your legal ID) and any nicknames or pseudonyms in the "other names" field,Not exactly true either. I'm pretty sure that Zoetica Ebb's real name is not, in fact, 'Zoetica Ebb,' and as far as I know she hasn't run into any problems, nor is she super-famous.
I think a rule of thumb seems to be if it is the name on your Wikipedia entry you are OK ;)
something that is obviously not a name
Robert Scoble has been one of the more outspoken supporters of this outside Google+ (although to be honest I know plenty of people inside G+ who aren't enthusiastic about it or at least would support pseudonymous use, at least one of them has been subsequently gagged), but even he has mellowed on this, although he says he does prefer the aesthetics of the place without all those weird names cluttering it up.
It seems to me that the most obvious answer then is for us to try to make you a page on Wikipedia.
I'm just waiting for my account to get flagged, if it does.
I wouldn't worry too much, as DavidLejeune says above they are currently picking off the most obvious pseudonyms, then they'll get around to the those rattling the cage (as they'll show up in a lot of Nym Wars threads and often have publicly declared on G+ that they are using pseudonyms) and then it is a longer more difficult trawl through what may be be around 2 million pseudonymous accounts. As this largely relies on people reporting accounts it will mean suspensions are going to be a little random, the problem I think will be that if you piss someone off and they spot you are using a pseudonym they could easily report you as revenge. However, if the name looks WASP-normal and you keep your head down you should be fine for now.
The thing is, you're looking at this as though there are human beings going through all the G+ accounts saying 'hmm, that doesn't look like a name to ME, *click send warning.* It's not. It's really obviously not. This is Google we're talking about. They're not going to have a person do something that they can have an algorithm do 1000 times faster.
