Based on Colin's
scoop on the illegal home-brew e-book of
Harry Potter and the Half-Blood Prince, Wired.com has a
follow-up explaining that the Russian website used by the scanner team to host the ripped e-book received 80,000 hits (before it was shut down by Rowling's merciless lawyers, I assume).
The article also mentions MobileRead as a place where e-book "enthusiasts" can talk about the "miniscule" (quote Nick Bogaty from Open eBook Forum) e-book market. Of course, if publishers and authors alike continue to refuse the release of bestseller e-books, its market will always remain just a drop in the ocean.
