1. I don't think any current language is worth loving, but for what I write JS sucks less than any other. It seems like the lang is a kind of programmer Rorschach test: there isn't really "the JavaScript way", it's what you (and others) make it. The interesting thing about reading other people's JS code is that I can usually tell right away which other languages they know (and those they don't). But that's just JavaScript; I prefer the AppJet framework to the other server-side solutions (namely Jaxer) and the web libs I've tried out for the langs you mention. 2. Once App Engine supports Java, one should be able to run "JavaScript on Jets" on Google's servers. Plus there's always AWS. 3. I've been using AppJet daily for almost two months, and I've only experienced a few seconds of downtime. Etherpad seemed to stay up. I trust them so far; two of the founders did work at Google.
