For all those that could be interested, I made oine of those new Twitter lists with people who talks about infographics (or are just great professionals on it, and although they don't talk too much about it, it worths to follow them just in case...). The name is very very original: infographics.
I'm sure I'm forgetting many follow-worthy people, so suggestions are wellcomed...
