-Why ES6/ES2015? Because I got used to it before. You can use Babel to transpile to ES5. - What are the advantages over Knockout? I didn't use Knockout since a long time, it was a source of inspiration, so I can't fully answer this question. DOM99 doesn't tell you to use the Model-View-View Model pattern, but lets you organize your application as you want. This can also be a disadvantage if you are doing it wrong for example. - Why does it weigh so much if its only ability is two-way data binding? Because you looked at source files that are not minified. - Why the heck do I need to use Browserify for something that will NEVER EVER run on a server side?! You don't need browserify at all. I wrote the readme a bit too fast and forgot to mention other methods. You can also load it like any normal js file. Hope I helped, I will update the readme in a few minutes to show how to use it without browserify. If you have other questions just ask.
