Angular 2.0 is backwards compatible the same way that React is compatible with Angular 1.0... basically it's mainly just the new Router that makes it possible to use other libraries easier with 1.0.
These are great times! Companies learnt that alone/closed/private doesn't drive innovation... You can see in the latest news many standards been made by the companies together... Working with docker for dev-environment has been fantastic (for me), really fast and easy to start/stop/modify different setups.
very well said! I've worked in a team and we used slack, exactly as you explained... we knew each other, it worked great with Hangouts, Bitbucket and Asana integration.
But for this use case in the post, it's obviously not such a great choice.
