I came across Ara Abrahamian's Memory Dump blog this evening.
I've been leading XDoclet for a long time. I'll post my thoughts about uses (and misuses) of code generation and Attribute Oriented Programming here. Stay tuned! I promise you'll be thrilled to know what XDoclet can do :-)
First of all, very cool that he's using Roller! Secondly, Ara - your template/site needs some work in Mozilla. Try it, it's about 30% wider than my screen - and I have to scroll over to read all your content. Works fine in IE (although a horizontal scrollbar still appears). Use standards and all your cross-browser problems will go away ;-)
