I have been finding more and more interesting eBooks for purchase online. But I don't buy them for a few reasons. First, without ratings by people with good reputation I have no idea whether the book is good or bad. In this case, Grady Booch gave it a thumbs up, but I would still like to see more endorsements / reviews. I know Amazon can be rigged, but for certain genres I've found individuals I trust. Second, my experience with self published books is that they are often pretty poor in terms of eBook production, even by good authors. I have books by good authors who have gone the traditional route and then tried self publishing; the difference is often night and day. Last, when I purchase an eBook, I like that it is stored permanently in some place online, so I can refresh it at will. When new formats become available, I want the option to download it for free. I'm not paying for separate PDFs and ePubs. Both OReilly and Informit allow this, and when new formats become available, its easy to get them.
