How come not many people have a photo of self on this single site You can’t see each other how can you tell if the person is you’re interested looks like words is not enough theses days
Well for me and I think a lot of the other people here, since we don't primarily come here looking for someone to date and most of us are unlikely to ever meet in real life, looks and appearances really don't matter much. And since this site is viewable by the entire internet, there's always the chance of disreputable characters coming along and we'd prefer not to have our identities exposed to such people or our images available to them. Besides you never know for sure if the picture a person has on their profile is really them or not (there are some good indicators, but it could always be their friend or something and not them).
Many of us are also introverted and value our privacy and anonymity on the internet. So even though I've been here for 5+ years now (I think), very few people on this site know my real name, the state I live in, or what I look like. But if I started talking to some guy here and we had really good conversations and I felt like I was getting to know him well, I'd probably reveal all of that information to him when it seemed either necessary or appropriate.
