If marketers can try to fool you into opening junk mail by disguising it as important legal communications, why can’t the opposite idea also work?

Here's a business idea which I think might actually have some legs in the right geographic location: the Techie Meal.

We've already got low-fare airlines dispensing with reserved seats, meals, etc. on many flights. What about the ultimate in no-frills air transport, the airborne equivalent of a city bus?

Instead of buying a ticket for a particular flight on a particular day, you buy a coupon for any flight between a given pair of cities. The coupon isn't tied to a given date or time (though it might have an expiration date): you simply arrive at the airport, and get on the next flight departing for your destination city. Coupons could be sold in ATM-style kiosks at the airport, eliminating the need to plan ahead, or in 10-packs for frequent travelers.

Here's the deal: let's say you've got a few grand in your savings account which you are saving up for a rainy day, but don't expect to need immediately.

Used CD's and DVD's appear to be an almost-ideal market for an exchange-style market, matching multiple buyers and sellers.

Right now, there are a lot of used CD dealers, and some auctions on eBay and similar sites. Used music (and movies) has all the characteristics which would make it a good candidate for a market modeled on the stock exchanges.
