Having used the site, no one puts contact information in their profiles. And a request to use the built-in chat system right away is a pretty sure sign that I'm not going to want to talk to someone. I'd bet that, to a point, there's a correlation between the volume of text sent and reply rate. However, that might just have to do with the fact that a longer message is more likely to reference specific things in the person's profile that they find interesting (for example, I replied to almost anyone who showed interest in the fact that I bake bread and like kites).
