Well I was excited about it, then @jensimmons blocked me (and a number of others) on Twitter and tweeted some pretty awful against men (and tweeting to people "No grid for you!" after she blocked them), and she's currently employed as a 'Designer Advocate' for Mozilla promoting stuff like CSS Grids…how does she keep her job!?
I bet CSS Grids will probably be great… but Jen's behaviour has really turned me off Mozilla as a company, and zapped 100% of the fun out of learning or using CSS Grids. I don't want anything to do with people/attitudes/behaviour like that! I can find plenty of other ways to build layouts that don't involve dealing with this sort of vitriol :)
