I've done a bunch of web development with JSP/J2EE and some ASP.NET. Nevertheless, I still feel like I'm catching up with the web 2.0 stuff that relies heavily on JavaScript.
I have two questions:
I'm looking for great samples of web applications to learn development techniques. I prefer to look at real-world examples (i.e. something open source). I'm open to learning from any great code, regardless of language used on server side. The kind of example webapps I'm looking for are ones that clean and not too complex, but also not too trivial. I have checked out some code from google code project hosting, but I don't have time to download and look at hundreds of different projects, so I'm looking for suggestions.
Second question: I know Ruby on Rails was an innovative framework (which I've never used, but I'm familiar with it and I've played around with Grails, a similar framework but more Java-like). So rails is now a few years old. What are the major things we learned since the introduction of Rails and what does the next generation of web framework look like?
