I agree with the point. But all i'm suggesting is just improve the rewrites you've already implemented in Reviewpost.
For example take this url:
w.omegatron.net/reviews/showproduct.php/cat/4/item/5_View of the lake and trees
This can easily turn to (using a .htaccess redirect) :
which is a near perfect implementation of a professional url rewrite. Look how good is the url now compared to the old one.
Meta tags are important, but more important is a good hierarchical URL structure. Fast and accurate google indexing, better targeted ads, all depend on urls. I am saying this based on my years of experience in running forums & blogs.
May I suggest to run an opinion poll for the customers here and see if they are interested. Just a suggestion, it's all upto you.
Btw. You're from Abingdon, Oxford ?
