The Knowledge Base only got subsections fairly recently (I don't know exactly when). Before that all those threads were in one area, what's now the general Knowledge Base area. There were no 'Questions for a Master'/Mistress/Slave/Switch areas.

I think I agree that it was better without them, since it's not like posing a question in one section limits the range of people who answer it(and it shouldn't), except that it's more tiresome to get to all the threads this way.
