Now everyone can sign up for Google+, and no more asking around for someone to send you the invite. Besides the news that Google+ has gone public, many features were also revealed, showing that the guys over at Mountain View have been really hard at work.
One of the many features revealed was the ability to search for anything from relevant people and even search within posts, and not forgetting this is Google we're talking about, your search will even turn up results from the web. And the best part is the results will include posts and updates that only you can see, so it 's not hard to keep in touch with your friends and family anymore (provided they're on Google+).
For more details on the features revealed, check out Google's blog.
