Not quite a bug, but I don't know what to make of it. When I read a review, I get a list of the author's connections. Since these are the people with whom the author can exchange private messaages, isn't some of the message privacy peeled away?
This is another display that I'm not interested in, done in pictures that take far more space than needed. But if you need to put something there, wouldn't a list of the author's (public) groups make more sense?
I'm a fanatic on screen space. It's the way my computer and your website communicate with me, and it's a finite resource.
Images have another cost. If I'm running on battery in a place where I'm relying on a slow wi-fi connection, they slow the page load considerably.
