Sweet about time! I have not looked into it much, but I am a big fan of ZF1. Now to sit here waiting for the usual PHP and ZF hate comments. Or maybe this time will be different...
I also really enjoy working with ZF 1. It's the best designed framework I've worked with. I've just had a quick look through v2 but it looks good from what I've seen. The namespaces really help to clean things up.
