Here’s a quote from story in NYT:
On the first Monday in June I checked the Kindle Single sales rankings, having last looked a month before, when “Boom” was still hanging on at about No. 40. Now I couldn’t find it in the top 100. Oh well, I thought, can’t be a best seller forever.
I then went to the Amazon page for “Boom,” to savor any new reviews. A message appeared: “We’re sorry. The Web address you entered is not a functioning page on our site.” I checked my Amazon author page, and then iTunes and Barnes & Noble. “Boom” had vanished. Poof. As if it had never existed.
…
Meanwhile, I’m back to planning my next book. I don’t yet know on what subject. But I do know its form: in hard copy, between covers, a book I can put on the shelf and look at forever, even if it doesn’t sell.
