Needs more description of why one might choose (or not choose) a particular tool. Readers already know "X is a framework" because it appears under the "Frameworks" heading: what is each framework good at?

More importantly, what isn't it good at - for instance, some of the bigger frameworks are tricky to integrate if you don't want to hand them control over the whole page.

A mention of JS debuggers like theseus might be good.

Would be cool to automatically change the URL to the anchor as I scroll.

How about https://moot.it/riotjs/ ?
