Mixed feelings on this, but, overall, I tend to agree with Chad (that was tough to spit out!)
On one level, I could see adding a PC Tech, and Hardware/Electronics forum, but I personally have had the following issue on here before:
My computer is doing something weird when I do something in MAME. It could be my interface. It could be some software setting, it could be my PC hardware or some BIOS config.
Right now, I have to guess whether it is most likely software or hardware and post it in either Software or Main. If we add more forums, then is this an electronics problem, or software, or PC tech, or hardware. I despise cross-posting, but sometimes that becomes the only way to find an answer.
The other problem is as trying to be a support person - I tend to follow Main and Software and Recent Unread Topics, and ignore monitor and woodworking, b/c these are not my strong areas. As it is, replies that are 2nd or 3rd on the Main forum might be 30th in recent unread due to all the other forum activity. Adding new forums adds 2 or three more boards to keep up with and complicates things, IMHO.
