OK, I had a laugh...
But, what about contributing a line or two on "what are CPLDs/FPGAs good for" into the FAQ?

PS For start, I can offer the following from the would-be wiki:

Field Programmable Gate Array - logic device, exact function of which depend on a setup. Typically they consist of relatively small cells implementing basic logic functions (a couple of gates and a flip-flop or so) interconnected together; the setup then selects which function of the cell is active and how it interconnects to other cells. Another type of programmable logic is CPLD (Complex Programmable Logic Device) which are usually of smaller logic density and don't implement too much sequential logic (flip-flops). CPLD originate in PAL/GAL (Programmable/Gate Array Logic) devices, they are formed by a large and-or array ending in so called macrocells (containing the flip-flop).

There is also a very nice explanation of softcores by Jez there, I wonder were could fit that one, I doubt it is really a FAQ, it's much more in-depth...
