|go ahead... be a heretic
There is a module that I've used for a long time, and I've never had any problems. For a while, it had no reviews. Then one day while checking the docs, I saw that someone had given it a pretty low score, and I was shocked.
I think you have to keep in mind that when a module does NOT do what someone wants, they complain loudly, but when it works great, no one says anything. It's like working the IT help desk - you only hear from people when they have a problem, when something's broke, etc. No one ever calls up just to say, "thanks! great job!" (although maybe they should!).
Unfortunately, this makes the ratings system kind of worthless....
But it also means that when I go looking for modules, I don't care what anyone else thinks - I try it and form my own opinion. All I really care about is if it works for ME. Hopefully others will feel the same.
