I am sorry about the caching problems, I wasn’t thinking very well about client-side caches.
This new site is definitely in an improvement on the homepage, features page, and download pages where content has been refocused, cleaned up, and reorganized. People literally were leaving the old download page because they couldn’t figure out how to use it. So far I’ve seen better conversion on the new download page, so that’s good. The new homepage overall has good reviews because people’s first question is, “What’s the flow/feel of this server, how does it work?” And I think it does a decent job at making that apparent.
The docs need some cleaning up, I also agree, and I’ll get around to it. I have some ideas in mind to make better use of the wide space that’s available.
Yes, the site is geared more towards decision makers: those who have purchasing authority and decide which technology to use. The User Guide (which, maybe @woubuc is right, should be renamed to Documentation – I always felt like “User Guide” had a classier ring to it) is definitely geared more for developers and the technical crowd.
