Hey Bay - or Hey! Bay, I haven't decided yet - is like Ebay, but for ideas. That's right folks, a trading post for concepts.
Ideas are priced according to their (i) specificity and (ii) replicability, thus:
"You could open a kebab shop?" Can be had for only 1p plus postage and packing.
"Hey! Bay: an eBay for ideas, where contributors buy and sell ideas depending upon their specificity and replicability. See attached pdf for fully costed business plan." ...would set you back £49.99 plus P+P, a steal I'm sure you'll agree.
The sub-pages for writers would be boss, let's face it.
