I don't see what the point is in this poll. First, similar polls have been done recently, so this information already exists. Secondly, that's a fairly small (and seemingly arbitrary) subset of the available choices... Why not include, for example:

Pylons / Pyramid

Wicket

Groovy on Grails

Stripes

Lift

Compojure

Spring MVC

Snap

and any number of other popular frameworks?

All of that said, my primary choice is Groovy on Grails, so I voted "other."
