It's definitely the most confusing one to me, and it only gets more so the more you study it. It's almost as if the circles were designed first, and then the groups of text were randomly assigned a circle. It's peculiar that stock photography and blogs are the biggest circles. Maybe they're what the majority of their users actually use the service for? Then there's the grouping and positioning. It's strange to me that Tumblr is in bookmarking instead of blogging, or that blogging is attached to postcards and image bookmarking and not blogs. Why are the things in bookmarking not grouped with Instagram, and why is Twitter with Instagram instead of Tumblr or Pinterest.
So I guess the main point they're trying to make is that you have to go to all these sites to do this stuff, but they give it all to you in one place. What's slightly strange to me is that there are a lot of sites in the problem area whose content isn't in the solutions area, so it's maybe not clear if this is providing some of that content or all of it. Maybe a clever graphic indicating logical process, like a funnel or something sorting and processing the problem balls for you as you scroll down would make more sense (and be less creepy than Daniel's blinking mug looking at me).
