Well, there was one nice person whom I did originally meet solely through bondage.com. And another nice person responded to my profile after having noticed me at a munch... we had also both been in the same local chatroom a few times. So the sites are not totally useless.

I am curious as to how collarme gets its funding, since they don't have paid accounts like bondage.com does, and they seem to only have a few small ads on their pages.
