The Facebook idea of "friending" means you find someone you'd like to share with, send a request to make the connection, and wait until it's either accepted, denied or ignored. Google+ works differently. If there are Google+ members you find interesting, you simply drag their names to one of your Circles and immediately start following their posts. This is a lot like Twitter, where anyone can follow someone else's tweets.
At first glance this seems like a privacy problem, but in practice it's not a big deal, thanks to the Circles concept. Sure, you can find my name on Google+ and add me to one of your Circles, but you'll only see the posts I choose to make public, not the ones I share specifically with members of my Circles. And as we know from Twitter's massive popularity, many people will welcome the opportunity to read posts from celebrities, experts and public figures on Google+.
