The bad: Google Employee "Bin" would like to Welcome us to Buzz. Since that original post Bin has been answering all kinds of questions on the "Buzz for Mobile" support forums. Including a question about why we need to make our full names public to post to Buzz. The bad news is that what has been troubling a lot of us was actually done by design. They want and require us to show our "full names." As someone pointed out though there's nothing currently stopping you from replacing your "full name" with a pseudonym of your choosing, at least not for now.
Likewise the Buzz Mobile app, which is integrated with the Google Maps app, is intended to only let you make public Buzz posts.
And the somewhat unsettling part? If you want to post on the Google support forums you need to have a Google account. When you post that post will be linked to your Google profile. So if someone wanted to ask a question or complain about Google Buzz after trying it out then their profile, including their full name, would be out there for everyone to see.
But at least that means that we can go take a look at Bin's profile as well. Turnabout is fair play and all, right? Funny, their profile says their first name is "Robin," but it doesn't give us a last name (and since their posts are showing up in the forums as "Bin" rather than "Robin" presumably they must not have the "show full name" option turned on either.) Likewise Christopher, another Google Employee who's been covering the Buzz for Mobile forums also has a profile with no last name. So do the people who are urging us to try Buzz and are trying to explain and justify Google's decisions about it not actually use Buzz themselves? Or do Google employees get exempted from the rules the rest of us have to follow? Or is this just an implied agreement that as long as the rules about profiles are so restrictive that it's perfectly okay to have multiple Google accounts so you can control what information others see about you?
I can think of a lot of different and very good reasons why Bin and Christopher might not want to be putting their full names up for everyone to see, but I think those same reasons apply to myself and everyone else just as much as they do to them.
