I agree good caches should be identified; however I think a rating system might do more harm then good. It might even discourage people from placing new caches. If we had to pay-per-cache then an overall rating system would be essential.
As an alternate approach, we all could award the great caches. It would be nice to see an annual Central Valley Cache Award Event and a Bay Area Cache Award Event. Several caches could be nominated in various categories and winners selected. A custom logo could be added to the page of each nominated and winning cache. This event might drive the quality of caches up without ruffling feathers.
Since I live in the bay area I have done very few central valley caches. The next time I drive out there, it would be nice to target award winnings caches. The same would be true when people visit the bay area.
