CodePen

CodePen –  “CodePen is a social development environment for front-end designers and developers. It’s the best place to build and deploy a website, show off your work, build test cases, and find inspiration.”

This is another top favorite of mine.  Their newsletters are jam packed with great info, podcasts, tutorials, lots of different projects that users have created on Codepen.  They also include jobs for Designers, Developers, and Engineers.  If you are interested in any of their meetup groups they are also listed at the end of their emails.
