Don't get fixated on the picture. Common sense will tell you that if there are results with pictures and results without then the picture might be one of the factors that encourages people to link, but it is much more likely to be if the person in question is in a larger number of Google+ circles, in other words, they have more endorsements from a community and if some of the circlers are in your circle of influence (search plus your world) then the likelihood is even greater.
As for people finding "content" I write most of my best pieces directly on Google+ rather than a blog.
You'll hear more about Paid/Owned/Earned media and the earned is the social stuff, the +1's, the reshares, the comments.
The signals coming from Google+ will continue to get stronger.
I've been hanging out (literally and metaphorically) with some of the smartest Google+ people, who really get it. They are dragging me along by my shirt-tails with the knowledge grab.
I love all that is happening on Google+ the negatives in the post starting by littlecubpanda are a little scary. I don't care if people click to find my content on Google+ and interact. I have a Wordpress plugin set up so that any comments appear on Google+ and vice versa. If they don't have any connections, then they should go out and create them, lots of them. Type in keywords that they are interested in and find the authorities on Google+ in the communities, on posts, there are a multitude of third party research tools that will help you find them.
