People are going to come to our site expecting to find information about equipment. This is the logical place to ask such questions.
That doesn't mean that we should accept such questions, but surely it should give us pause to think about what are we offering?
Choosing equipment is a major part of photography, and to ignore this would make our site less than it could (should) be. Of course, diluting our site with off-topic, un-answerable or too-localised questions would also be detrimental.
If we just point people to google, they don't know which reviews are trustworthy. I.e. there is too much noise.
Perhaps we could solve the noise problem by having pointers to good review sites?
For example, would it help to have a question which solicits a list (or index) of trustworthy review sites? Then when someone asks a review-type question, we could close their question and point them to our "index" question?
Fortunately, @Eruditass has already asked this question, which seems to be exactly what we need.
