Little substance is found in Top N lists. I would much rather have the author cover one library and explain how it has benefited his development process. What roadblocks did using xyz library overcome? What issues were found along the way? It is like providing a list of simplex algorithms. This is a simplex algorithm using divide and conquer, brute force, blah.

200 words on one library provides more insight than 'XYZ Library: A library that does XYZ for people that do XYZ.'

Lists rarely spark insight, but knowing that Bob overcame a barrier with Canvas by utilizing XYZ library, that's gold. Hell, I might even use XYZ to try to attack a similar problem.
