During the last 18 months, vendors have come to realize that advertising on Websites doesn't work at all. You can verify this by counting the number of times you've bought anything by clicking on an ad you saw on a website. Most people I've asked say 0, 1, or 2 items, with a heavy skew towards zero.

For publications in markets with a large number of vendors, the pool of vendors who still see advantage in web ads (such as ads that don't expect purchases, say, as for an upcoming movie) will sustain them. But the software development tools market is small with fewer than 100 vendors, many of which don't advertise at all.

So, essentially, there just was not enough advertising to keep us going.
