When writing things like this you have to tread a line between "I am somehow an expert on Everything, trust me" and "here's 200 different libraries, and sixty pages of reviews and benchmarks, it's your choice in the end".

The latter is basically in the situation when you go to a Cliki page[0], or when someone on freenode/#lisp asks what library they can use for X, and was what I mainly wanted to avoid.
