Whilst I agree that simple anonymous voting would be to capricious, I think getting a list of the great and the good whom would be charged with the responsibility of reviewing modules could be equally so. Not to mention that the people on that list would most likely be too busy to devote time to such endevours.

Perhaps a mechanism whereby anyone could attach their experiences of a module to that module, with a consideration mechanism to exclude obvious trolling and an anonymous voting mechanism on reviews posted that would provide peer review of the reviews, with obviously discordant ones (large negatives) disappearing.

Now it starts to look complicated. I guess it's likely to remain "Caveat downloader" for the forceable future.

It seems a shame that there isn't a simple way by which the seeker of the module can gain from the experiences of those that have gone before in their attempts to choose any given module or type of module.

Examine what is said, not who speaks.
