I'm not generally a big fan of infographics. I basically consider them the "lolcats of dataporn", if that makes sense - cutesy pictures that appeal to people who are obsessed with the act of acquiring more information, but never really figure out ways to use it in any way because they're too busy acquiring the next piece of dataporn.
However, sometimes, an infographic can be a great way to explain an idea visually. That's the case for this one, by Jess, reposted by Mark Suster, which conveys, both visually and with numbers, how share dilutions work in practice.
Enjoy, but don't let me catch you watching porn again!
