Just over two months ago I posted about a new rapid Web application development framework for Rails called Hobo. The team have now let me know they've got a brand new, redesigned site, and that Hobo has a major, new release.
Hobo makes it really easy to get a basic Web application up and running in Rails. It's a little like scaffolding but with a turbocharger under the hood. And if you want to get up and running in just a few minutes, they have a short tutorial along with three screencasts.
