Do you think that is better than posting on the existing thread?
Absolutely I do Rico. Think of it like this - you're looking for a punt and spot a candidate on AW etc. You search on UKP typing in the AW Id, or something likely to find reviews for your target. Your results show discussions and reviews; you quickly form a view of the SP using the number of positives, negatives and neutrals and checking out a few recent positives and see the services you want are or are not discussed as being offered. You add the girl to the shortlist and look at the next candidate from AW etc. Rarely in this process do we read whole reviews; that's for leisurely Sunday morning reading.
So the way I see it, separate reviews give more material for forming an opinion, more quickly, and sometimes time is a critical factor. This is why reviews, more than extended comments are a much more powerful decision making aid for punters.
The very worst are those non-reviewers who pop up on someones review and say, "oh yeah, saw her three weeks ago an she wur crap" Once counted five comments like that on someones first negative review
