There is this very popular place earlier known as Hacker School and now known as Recurse Center at NYC, so if you can manage to arrange some place to live in NYC I suggest you to go and check out this place. It's community driven and ask for no fee though is very good and worth giving a try. Here is the link to the same https://www.recurse.com
As many said before I think going for a custom domain and using Github Pages with it would be great idea and to get proper audience for the same you can post the link on different relative forums.
I think the Mozilla's MDN https://developer.mozilla.org/en-US/ is the best for web stack, for others keep an eye on HN new posts everyday there is one link to new blog for sure :)
here I also found this website http://codingmath.com where they only teaches you math and how to apply it to program i found it very interesting. you should give it a try too.
you can visit http://functionspace.org or Khanacademy.org both side provide amazing stuff like video lectures, materials, articles etc for all level starting from very beginner to advance to Experts. Good luck :)
