We'll think some more about how we can communicate the concept better. Furthermore, we might have to delay the request for mic/camera access as it could scare people away (other have pointed this out as well).
I'm not too fond of changing the tagline to something referencing chatroulette, we're kinda hoping people will not directly associate our site with nude guys ;) But rethinking the tagline might be wise still.
Also, I think you're correct in pointing out a non-video way of getting the site explained is necessary. Perhaps just in words, or otherwise using graphics/drawings etc.
And indeed, we figured this will probably be used for dating-purposes a lot; so we'll try to make sure that is possible on BP.
Once more, thanks for your feedback!
