Thanks! And, yes, it’s a real fact that Edge has a slice on today’s browsers usage and soon this slice will increase; as developers we can’t ignore it and leave those users without a great navigation and a seamless experience. But, (that’s my opinion) I don’t feel Edge as part of the modern web. Even Edge 10 offers support for the most CSS and JS "new specs", it still looks like IE in many respects. We can expect a great different picture in the near future (and I hope so);
Also, in most projects I worked, the usage of Edge was literally about less than 1% — and it still happens.
