I have to say that I have felt all three - jealous - only with one and that was way weird!!! Competitive, as I couldn't schedule an appointment with some ladies when I wanted and you always want to be better (an ex jock thing I guess) But for the most part - if I read the reviews of others on the same girl - it tends to bring back the moments and I can rejoice with my comrades (haven't had any ROB's or really terrible experiences thanks to TER and the brethren)

I don't follow the reviewers for the reviews. When researching and a provider does not have many reviews, I also search other reviews posted by the same person. One example that stands out is a gentleman had 5 reviews posted - and in each one was the ending phrase - "It was the best time ever" or something very close. In cases like that - I tend to discount that opinion and probably would not see the lady until more reviews are posted.

That being said, if a person is an active participant in the board - be it client or provider - You are able to get a general feel for who they are. I can form my opinions about the individual and that will help me to come up with a trust factor. For example - even though Riker is the mod - he has done many things to make the hobby better such as pointing out ROB's bait and switches etc. If I were to see a provider profile with
only one review - and that reviews happened to be Riker's - I would trust the review and if I liked what I read, I would set up an appointment. On the other hand if the one review were from someone that wasn't a participant in the board, and all of thier other reviews were very close to the same - I probably would not set up an appointment.

Yes I do feel a comaraderie and do appreciate honest but polite reviews of women.  If a reviewer has many reviews I check that out too.  If they are all low that says he may be a very tough reviewer and if they are all high- that says he may not be very discriminating. No jealousy.  
It is nice to find another who has the same taste in women as I do and the reviews have led to some nice private e-mails and intel on who else fits our criteria- give and take.
