As John says, different people will place different value to different
differentiators.
In _addition_ to John's list, I'd also add:
* Downloads - In december we had at least 430K d/l - this was partial
due to a change in reporting machinery. As soon as I have more complete
numbers, I'll report them. This is substantially larger than JBoss (as
reported by SourceForge) and Geronimo (as reported by Apache stats).
* Velocity - We releasd GFv1 in May 06; since then we have released GFv1
UR1, GFv2 and GFv2 UR1. We are now working on GFv2.1 and GFv3 (modular)
* Up-Market - SIP Servlet support and Telco Support via SailFin
* Down-Market - Very small footprint and flexibility via modularity in GFv3.
I'm sure I'm missing differentiators...
