Man, if it's tough to get programmers to buy a set of custom controls or developer tools, it must be ten times more difficult to get them to buy an eBook. I'll admit, the site does portrait credibility.
I thought that too, but I think the difference is that a developer could look at a program and say, "hey, I could build that" but with a book they might not see it the same way.
No way, I buy lots of eBooks. I consider them a cheap education, especially with some of those great $10 deals that some publishers have for modern titles (e.g. friends of ED, Manning).
