Improvement #100. Anyone can sign up for Google —no invitation required.
For the past 12 weeks we’ve been in field trial, and during that time we’ve listened and learned a great deal. We’re nowhere near done, but with the improvements we’ve made so far we’re ready to move from field trial to beta, and introduce our 100th feature: open signups. This way anyone can visit google.com/ , join the project and connect with the people they care about. (via Official Google Blog: Google : 92, 93, 94, 95, 96, 97, 98, 99… 100.)
Not quite everyone, they forgot to mention that it still doesn’t work with Google App Accts!!!
Google has also released the Google+ API, tho without google app access, seems a bit of a hobbled system.
