I think the status quo is fine. Tim's approach is a bit dated, but it worked well for me.

But times are changing and "Information wants to be free".

It is just a matter of time before some young blood takes up soaring, evaluates the status quo, and with absolutely no compunction decides to set up a master compilation website on an offshore server.

That website will scrape ALL of the ads for gliders from ALL of the sites that accept ads. It will catch on fast because it will be the definitive master list of gliders for sale, and it will have a lot of the modern features that we see on a site like glidersource.com

That website will not accept ads from sellers, so it will not be possible to punish someone for posting. There may be legal IP issues, but those are rather difficult to enforce, and easy to sidestep. To create a cash flow to cover expenses, that website will accept banner ads selected by Google. People buying gliders have disposable income and they are good prospects for a variety of high priced products.

I'm old fashioned about intellectual property and so I would never do this, but you know... kids these days.

If the person behind Glidersource had not made the mistakes of 1)accepting ads and 2)personally identifying himself, we would already be seeing this master list of gliders for sale.
