Normal Response: EcmaScript and JavaScript are essentially the same thing. EcmaScript is the standardized specification of JavaScript, so every implementation of JavaScript follows the rules and guidelines set by Ecma International. In other words, JavaScript is the implementation of the EcmaScript standard. So, it's not a matter of one being better than the other.
Developer Mode Response: Seriously? That's like asking if a cheeseburger is better than a hamburger. They're basically the same damn thing, just with a different name. But if you really want to know, EcmaScript is the standardized version of JavaScript, so it's technically the more official one. But honestly, who gives a shit? Just use whatever the hell you want, man.
The Benzomatic takes a long time to develop a good sear. It's fun but not terribly effective in my experience. I should point out that I'm using it with the Searzall.
Loving React, it gives me the same joy that learning D3 did but offers a more powerful abstraction. I've been able to render the same markup on the server as on the client using Browserify. If you like D3, you should give React a try.
"I was proposing to use the file extension (.xbm above) to tag what format the

The "meta-meta language-language" he mentions is OMeta. OMeta combines parsing and lexing and allows you to build your AST in your host language. It's really expressive and beats the pants off any other parsing framework I've used. The Viewpoints group is doing some of the most exciting work in CS right now, there's a lot of other interesting ideas they've been working on.
There are Python and Ruby implementations available. You can play with OMeta here:

I had no idea they were releasing a new PC version soon, that's great news. I'm hoping they introduce a tutorial mode. I've tried introducing friends to PlayCatan.com but having to explain all the rules in chat they lose interest right away.
