I posted this comment on the Florida site; but I feel it has more validity here.
TripAdvisor, has the tourist area restaurants and hotels, etc petrified. We returned last month from a 4 week trip to Germany and Italy. Almost every hospitality business; restaurants/hotels/rental apts/etc. all asked us to please give them a good review on TripAdvisor. This is the first time that I noticed the intense pressure on establishments for "a good review". I think the value of these review sites is being compromised. I find more success for what I am seeking with Blogs i.e. Katy Parla, Elizabeth Minchelli and their ilk, than the mega sites
