I find myself spending a lot of time in Google+ and eventually running out of content that I can see from my friends or even incoming shares. I want to discover new content and new people in Google+ the same way I discover it on Twitter. So I hope Google will make the search bar work for content shared within Google+ as well, not just for people. Doing this would get people to spend even more time on Google+, reading other people's opinions or discovering their shares, and perhaps even meeting them through it. I want to read more content from other people on Google+ and I can't right now because I don't really have a good way of finding them. I hope Google was already thinking of activating this, but they didn't because at launch there wouldn't have been much content anyway. And before anyone starts saying I should use Sparks, it doesn't work the way I'm suggesting. Sparks is more like a Google search. What I'm asking for is searching within Google+ for shares and people, just like on Twitter.
