Contributions to the Awesome Developer Resources Article.

Hey guys, I just recently posted an article Awesome Developer Resources, where I created a list of resources that I think many developers would find useful, and in the comments section, someone added a link to a great resource for me to add to the current list. So I thought why don't I just provide the link to my Github repo and people can send in PR's of any great resources they know and I can just merge it. there's a poll above, please let me get your feedback. Thank you
