Hey guys - doing an interview with Vinai Kopp today who is building mage2.tv which is like laracasts for Magento 2. He's a veteran in the Magento world and I'm sure can answer most m2 questions that you would throw at him. Also if there are specific requests for video content for him I can pass those on. I'm not gonna link to the interview because I started getting down voted for that I guess for self promo but if you post questions in here I'll ask him and report back.
I upload my projects via StoreManager. And import spreadsheets like M2_Simple_Association are saved online too.
