whoever or whatever team came up with the personal README's for ones github profile needs to be given the keys to all of Github because no feature in all of my years of using github has had such a profound "cool" factor than this. It will also go a long way to solidify the site as a social network. I see it replacing my resume, I will just send people that link, much like I used to with a personal website.

The roadmap is nice and it's nice that we might get to see what is going on or coming up and maybe have a say in it. This seems a lot like what Gitlab is doing though, so perhaps they're trying to get some of Gitlab's goodwill?
