Even listing several types of applications that you can build with a “2nd generation wiki” is kind of selling it short. You should be able to build nearly ANY web application.
Also, I’m not a fan of AWM, or at least the FAQ Tutorial that uses it.. When I tried it, I thought “wait, I didn’t just build an app, I just pulled together an app that someone else has already built”, and felt let down.
What I would really like to see is the “FAQ Manual Tutorial” enhanced to include not just two text fields, but a whole bunch of fields. For example, a “Contact Manager” app where the Person XObject has name, age, sex, etc. And present it as “How to build a full application with XWiki”. And list the ability to build a “full web based application” as one of your Features
