My take on Module Reviews is that a lot of the modules on CPAN have fairly good documentation, including tutorial-like introduction.

What they lack is 3rd-party evaluation. Something along the lines of "don't use this module under windows" or "I found this module worked fine under mod_perl", or even "this module has some flaws but I found it worked for me in most situations" or "this module is hopelessly bugged and the author never answered my email". That's what I appreciate in Module Reviews: a user view on the module.

If I determine from the review that I can use the module to solve my problems then most of the time I will figure out how to use it.

Oh, and non-obvious tip is welcome too of course.
