Stock market are well suited to the buying and selling any classes of
items which are identitical, eg, equity in a company, futures contracts,
commodities (beef, gold, etc) and are more common than may you at first
think. The auction model is more suited to individual and unique items,
eg. antiques, spectrum blocks, second hand goods, etc. Both are open
makets though. In the middle is a whole range of markets including the
one you bought your new fridge in. There's certainly a lot around on the
theory of designing a good auction just type "auction theory" into your
favorite search engine or look at wikipedia's page on the subject
http://en.wikipedia.org/wiki/Auction_theory The most common market at a
guess would be those in the middle either B2B or B2C trying to find a
plumber, a new desk, or a manufacturer for your new widget. So if your
shooting for the potential size of audience that's where you'd aim, but
I think that is also the weakest in that it is ill defined.
I suppose comes down to finding a topic which highlights Erlangs good
side, inspires the potential reader to buy the book, motivates the
reader to try things, and proves valuable as a reference far into the
future. As such I'd rather any proposed book not be too heavy on the web
stuff and much more on the infrastructure side of things.
That being said I don't think either the auction or stock market ideas
are bad and it would be nice to see something less teleco/web industry
centric discussed in depth.
