Well, I do believe it's good to have a framework section, because most of the time (junior) developers face problems using certain frameworks that already have been explored by other (more experienced) developers.

I agree it shouldn't become a way to compare one framework to another, but merely to tacle challenges within each framework setting.

I also know that each framework has it's own forum or wiki for the discussions, but I do believe TalkPhp can become a reference for all php developers and a first base to start the search for knowledge.

Just my 2-cents
