I was originally put off by having to use my real name at first too (especially since it doesn't say how it's used). Turns out they use your first name and last initial although I'm not sure if this is shown to other members. I believe this is what Yahoo uses also.

I can see how this could be a turn off to some people but realistically if you're serious about online dating, your profile probably needs at least one good photo to yield any worthwhile results. And they're required for this service as well.

match.com uses usernames instead of real names but I don't need to see a person's first name to recognize her from the cube down the hall.
