Ooooh I like this game! How about now? https://www.google.com/trends/explore?q=ember%20js,react%20j...

I like how they solved scoped css. Looks way more elegant than most css-in-js solutions I've seen. I could give it a shot for this reason alone.

Always one of my favorite features of riotjs

Web components and polymer solve this problem "completly" by full encapsulation.

With some css preprocessing + vulcanizing you can even use separate js/css files from your component templates if that is your thing - they can get inlined in the build process.

Angular2 is doing a similar thing.

I got malware warning on Google Reader today. I wonder if this is related.

I just got one on YouTube, weird...

I'm going through your tutorial at the moment and I think it's excellent. Now I'm considering buying the updated screencast. One question though. Is there any possibility for kindle friendly e-book?

Many Kindles can read PDFs, and the Rails Tutorial book is designed to look good on those. Eventually I may release a mobi format as well, but it's a pain to make, and I find that both mobi and ePub are rotten formats for technical books.
