Here’s a separate thread for people most interested in keeping track of official, semi- and unofficial pronouncements about pseudonymity and/or privacy on Google+ in particular, in addition to the more general discussions taking place at Anti-pseudonym bingo and Social networking requirements. You can also discuss your feelings and reaction to various announcements here. warped-ellipsis, you can re-post your existing links in this thread if you like.
If you’re linking to a blog or Google+ discussion, please also include a summary or excerpt that explains why you’re linking to it. Is it a user test showing such-and-such a property of Google+? Is it a statement by Google or an employee? Is it a change or a clarification? That sort of thing. (No linking/quoting anything from G+ that isn’t marked “Public” please.)
Note: yes, Google+ is in beta/early launch/testing/something, and they’re actively seeking feedback. Please no nagging to people to send in their comments here as feedback, since they now know this for sure and presumably they have or will send it in if they want to, and if they haven’t they presumably have their reasons.
