Infographics Hub was the one that I chose and I wasn't all that impressed. They had some nice graphics, but the ones that I chose to look at had some information that was wrong. How do I know? Because I'm a huge Game of Thrones fan and they had two of the ruling Houses mixed up on their graphic, which was pretty blatant - also two houses you SHOULDN'T mix up, honestly, with one being a dragon and the other a stag. But enough about my nerdiness.
I guess I was disappointed that you couldn't make your own graphics with this one. I could look up graphics by category, which was nice, but I couldn't tweak them or edit them, which made some of them unusable for anything I might need an infographic for. These were cute, but really only useful to send to someone else or post online as a silly thing for friends to comment on.
I'm sure there are some with great information, I just didn't find them. There may be a few hidden gems in here for people to seriously use, but you'd have to wade through a lot to find them.
