Well, OpenACS 4 may not be a production system but if we put our energy into 3.2.5 then it never will be. We don't have the people to do both. 3.2.5 is getting bug fixes, and that's it at the moment.
(and OpenACS 4 actually *has* been used on several production sites - in Oracle, not Postgres. The Oracle version's in reasonably good shape).
dotLRN will be providing an entirely new portals package for OpenACS 4. I think it's fair to say that we're well aware of the importance of a good portals package and I think the new one shows promise.
And Michael's right about UI issues. One of my priorities for our second development cycle will be to improve the UI, as well as "under the hood" issues. Ideal would be to try to set some UI standards and then to get some end-user documentation going while we're implementing them.
