I think that forums in general are set for a revolution pretty soon - they are still in the same 10 year old format, pretty soon someone will come up with a better way of displaying this kind of info - the technology is now there - someone just needs to implement it. Despite orca's failings, it is actually an attempt to take some of this technology (AJAX) and apply it in improving the user experience, obviously this has not been completely successful, for a number of reasons, some things are great see more - such as the forum spy, but other things suck - like the AJAX post submission.
