Go is a web application server framework. It combines concepts found in the Zope and WO frameworks.
Its unlikely that you want to give it a try, unless you:
- Like the WO component/templating system
 - Don't want to use WO for whatever reason (otherwise just use WO)
 - Are not interested in 100% exact WO compatibility
 - Find Java as a programming language tolerable
 - Do not expect a shrinkwrapped product
 
If all that is OK with you, Go, give it a try ;-)
