I personally have 33 of those books in digital (PDF) format, and have read 6 of them. So far I can say, I have learned pretty much nothing more then I already knew before I read them. To be fair I have learned a few things, but nothing earth shattering. I know the amount of time I have spent on those books is quite large, and my wife can vouch for the time I didn't spend with her since I was "Learning" again.
Most of the content in those books looked like a copy and paste exercise from someone else's work. And don't get me started on the "code" samples. I think if I see the variable names Foo and Bar one more time I am either going to throw-up, or poke my own eye's out! It's almost as bad as the Northwind database examples... no it IS worse.
Seems the norm now is if you can't get or keep a programming job you start writing books. Or worse yet create your own "Framework" or "Library" and pass it off as something "New". AND worse yet is how many programmers are following these people right off the cliff.
I know we want to create great web sites, and in a timely fashion, but let's do our homework people! No matter how much it hurts to read these tomes, we still need to do it. How else are we going to know if it's crap, fact or fiction.
Well time to get off my soapbox for today.
Have fun programming, and Keep It Simple, Stupid.
