Hi Ryan,
In your early stages of site-building, you could try hooking up with some of the folks running Darwin-related websites listed in the Netscape Open Directory Project's
Darwin Directory. Also, I guess you could even try partnering in some way with Jason McIntosh, whose
Mac OS Open Source Software website is currently oriented more towards Mac OS Classic than X.
As Mac OS X becomes entrenched, no doubt there will also be many more non-Darwin open-source projects coming down the pipe (e.g., NeXTSTEP/OPENSTEP ports, and new Cocoa efforts). Actually, there are even some dedicated Cocoa development websites out there, such as
Cocoa Dev Central. Sad to say, I myself don't have much time these days to devote to Mac OS X programming, although that may change in the near future... In any event, I wish you all the best with your new website.
Regards,
