A WG who provides a positive service to a load of guys should get the benefit in terms of multiple good reviews IMHO
You are of course correct. Casandra consistently provides an excellent service, leading to plenty of positive reviews and is very popular on the back of them, so in that respect they've already served their primary purpose all round
But I'm thinking about the additional information which has found no single home.
When a review about a service eventually morphs, as they do into one about 'difficulties to contact', 'how long in advance we've had to book', 'actual duration of a 90 minute service', 'is she/isn't she on holiday', 'price increases', 'possible cameras next door' or even 'should we be posting this on the review board or the discussion board' then perhaps posting this information across several different reviews is no longer the right place
Actual experiences with a SP, good and bad, always deserve a review so we can all benefit from the collective knowledge, but if the more general information and questions were put on a single discussion post then it would make it much easier to find and digest, saving us all from trawling through multiple individual reviews for scraps of information
