My only complaint with G+ is the same one I have for most contemporary 'social' products: inability to select a specific user name. I would sincerely appreciate it if someone could enlighten me as to why I am almost always forced to identify myself as something other than rch. Are random or numeric account IDs really so bad? Were there problems with early products like ICQ? Quick edit: I know they dropped the real name requirements - I'm wondering why a unique, random account id couldn't be associated with one or more aliases, gmail addresses, etc., which could be aggregated, archived, hidden, dropped, and so on.
