I don't need another Chrome clone and as a developer
You can build on top of Blink to, for instance, either load images, or text first .. the caveat being of course, that Blink has actually slowed down over the years, so loading either text or images first could essentially be considered a non-starter. Rendering engines are much the same as operating systems in that as time progresses, they become burdened with back-web and bloat.
Since web standards have become more aligned, web browsers are becoming more and more the same regardless of just which rendering engine is chosen to do the job.
There's no reason why we should be pounding sand over today's rendering engines when we've got the web standards of the day to consider.
Microsoft has simply high-graded a build written by someone else and applied it to their own either real or imagined purpose. Short of branding, we're all using the same 1.3 litre engine to power our car .. the differences are only cosmetic .. different paint colours, tire sizes, seat positions, left or right side wheel positions, and it all rolls downhill at the same speed on the same day at the same time. As memory serves, even Opera dumped Presto in favour of Blink ... because, presumably, it didn't want to be found rolling down the same hill any slower or faster than anyone else.
As with anything that might be popular, Blink has slowed ... as far as use of resources are concerned, I'm of the opinion that Gecko and Blink are neck-in-neck on the course with WebKit in a not-so-very-distant second place. (no offence to all of our MacOS fan-boys out there)
The story of the day should be the much more aligned web standards we all seem to enjoy ... Browser rendering engines have little or no practical relevance these days when it comes to the web standards we've all fought so hard for, and have gained, over the years.
Currently, it's all just branding and hype ... a clone of a clone of a clone is essentially all that Blink has become .. and that .. on the face of it .. makes my job as a developer, that much easier, in that now I have one more "clone" build that I can basically just ignore.
Anyone know the web saturation of Edge these days?
IMO I think it's too early to really tell. I can say though, that Edge hasn't had the same affect on the webs that Internet Explorer did back in the day against Netscape ... It took less than a year for Internet Explorer to dethrone Netscape. I'm not seeing anything of the sort happening now with Edge -- For as long as Edge has been released, it still stacks up last place behind Google Chrome, Safari, and Firefox..
