I am a fan of Jeffrey Richter and Joel Spolsky.
I like them particularly because they have a marvelous writing style (the fact that they really really know their stuff goes without saying).
Both Jeffery and Joel for me have the ability to explain complex ideas in simple ways. Which for me is the key. Joel actually goes one step further and makes it entertaining.
The question popped up as I was looking for a book in LINQ that was well written. Had there been one authored by one of my favorites I wouldn’t have had to think twice.
It would be nice to know if there are other technical authors out there that make technical books readable cover to cover.
