Up front I give this site 5 stars. I am astonished that it is not the most popular site. Why: because it is the only free site that I have found that gives basic real contact with other participants, which just does not exist at any other site that I have looked at. No one seems to make this fact clear. You can pay for more features, but the lack of these features does not prevent you from making real contact. All the other sites want to charge you as soon as you click on sending a message and want to lock you into automatic renewal at substantial rates. In fact, looking at the reviews of these other sites, it looks as though they are being run by con artists. The constant changing of the cost at these other sites also suggests that they are trying to manipulate you.
As to the people presenting themselves at OKc, I have not found any evidence that it does represent the normal spectrum of people that you meet in every day life.
My suggestion is that you try it. I wonder if the negative reviews have been submitted by the other unscrupulous sites. It is well within the domain of a psychopaths.
