Here’s a quote from the post:
“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.”
