When I first began researching Linux, for my needs, I found the number of different Distros to be overwhelming. So I made this flow chart, with the intent to help new users find a starting point for choosing a distribution.
I'm open to critique, as to making this chart as helpful as possible.
EDIT: Chart updated based on suggestions in the comments.
I like your approach in that they don't all just flow to the same 2 distros and there are multiple options at the end of most lines. It's also quite readable. I do think there's even more room to just try stuff out though, distros are not particularly rigid, certainly not when you're first trying them out and you don't know the differences.
I happily use MXLinux to game on new(not so new now I suppose) hardware, run a media box, and on a couple work/school laptops for example. It's just what I tried and felt cozy with after I got angry with windows and mint. I'm sure other distros are technically better for my uses but nothing I've tried has really been so much better to justify the switch.
