I don't know if you already saw the "beta version of the new asktom interface"? I find it cool! You can see the new askTom here.
I've the impression that this askTom is more integrated into APEX and uses a lot more features that come "out-of-the-box" with APEX. For ex. the use of theme 18, tabs, breadcrumbs etc.
I really look forward to dowload this application from the "Packaged Application" page on the APEX OTN page. The application is called "Ask the Expert" and has following description:
Ask the Expert is an application based on Ask Tom (http://asktom.oracle.com/). Using this application, users can post questions to an expert and the expert can answer. The application is powered by interMedia for text search. The expert has the full power to control the application. They can limit the number of questions allowed and block new questions completely. If the question is found to be useful, it can be published so others can view it.
