Randomly match three half-baked ideas from
halfbakery.com, using a server-based application. After all
possible combinations of three ideas have been created,
the results are run through a grammar-checker, then
passed along to low-but-fairly-paid workers in third world
countries, and perhaps
second and first world countries as
well.. These workers would throw out combinations that
made no sense whatsoever, and allow the remaining ones
to be committed to the database.

Dedicated users could then go through the results: the
chances are good that putting together three half-baked
ideas will result in an idea and a half at least some of the
time.

Revenue from these amazing ideas would be used to
provide wages for the dedicated workers doing the sorting.

I think it might be asymptotic. One idea is halfbaked, the second idea would occupy half the distance between the original idea and bakedness and the third cover half of the remaining distance, and so on.

I think it's multiplicatory too. Imagine every idea exists somewhere on a scale from "completely shit" to "genius!", where "completely shit" is 0 and "genius!" is 1. Then, when two ideas are brought together, you multiply their scores so the resultant idea from the combination of two ideas with scores of 0.4 and 0.9 would be 0.36.

It might depend on the idea. Maybe there are different operators influencing how the ideas behave, so one way of combining ideas is akin to multiplication, another to exponentiation and another to addition. In which case, maybe group theory can be applied to the HB.

Hmmm... it sounds like we have uncovered the potential for a whole new branch of mathematics. With numbers, there are operation symbols that affect the way the numbers are combined. For example, 36 + 26 + 36, 36 x 26 x 36, and 36-26-36 all have different meanings.

Similarly, the way half-baked ideas are combined will affect the outcome. If they are layered on top of one another, with the heaviest on the bottom, it would be different than if they were folded gently together using a large spoon, or beaten with an eggbeater.

Perhaps all of the letters could be sorted alphabetically, and then fed into an anagram generator. The result of this would be nonsense at worst, and, perhaps, humor at best.

So you assume that HB ideas are endarkening rather than enlightening? Subtractively, that's what you get but additively you'd get white. That would mean that reading the HB too much would remove intelligence and be the opposite of educational. Hmm...
