As a relative newcomer...
...I do not find the site cumbersome nor difficult to navigate. Granted, there are a large number of forums but isn't that what the site's name suggests: Forums. A plurality. I don't believe this site was created to serve the wants, needs or desires of any one single photographic endeavor. If you're interested in Portraits, then spend your time there. If larger formats are what you practice, then there's a place for you to share your work and knowlege, etc, etc.
I don't know how others navigate, but as for me the first link I select at every visit is "Recent Posts". You've got a snapshot of everything that's happened since your last visit. How can you make it easier than that?
Asher, please choose your changes with care. This is a splendid forum with genuine heartfelt conversation shared between participants. I imagine you and others placed a tremendous amount of sweat equity into its creation. Do not change for change sake.
Lastly, this may not be the place for everyone, nor will everyone find this place satisfies their needs. There are many forums out there. I'm sure they'll find the place that makes them feel most comfortable.
