Unfortunately, I have to lock some premium content up back there. I have to sell books, or the lights go out. It’s the only viable alternative to running ads on PainScience.com … which I will never do, because “lousy ads are ruining the online experience,” and I do not want to contribute to that, no matter how much money I’m leaving on the table. Which is quite a lot: I have the traffic I need to sell out in that way. I just couldn’t sleep at night.
Ads make me grumpy. Paywalls make me grumpy. But paywalls make me slightly less grumpy than ads.
Which is why I share some excerpts here — in an ephemeral, limited fashion that isn’t going to kill book sales. 😉
