I'm conflicted about this. On the one hand, it seems like a good idea to test your product ideas in this cheap way. On the other hand, you could easily miss great products that just need a little time to catch on—some products don't lend themselves to an immediate decision based on some web page ad copy. For example, in Founders at Work Joel Spolsky talks about launching FogBugz: We had no idea [how FogBugz would do]. At the time, you could have told me that this thing was going to sell zero copies, and I would have believed you. You could have also told me it was going to sell $50,000 a month's worth of copies—an equally unrealistic number—and I would have believed that too. Now I have enough experience to know that almost everything you launch is going to sell $2,000 to 3,000 in the first month, and that's the way the first month of any software product always is, if you do things perfectly. But at the time, I just had no idea what to expect.
