I'm pretty familiar with the online dating industry both through business and my own personal involvement. While I agree with the issues that you raise (POF, for instance, has 6.6 guys per girls the last time I checked 6 years ago), I don't see how a new business model will really address this. Attractive women are being wooed all the time and that's not going to change.
I think an online speed dating service for business professionals, however, would do well. I believe that there are services like this out there but none of them have achieved a true following I would argue.
Imagine logging onto a site where with use of full audio and video you meet 10 eligible bachelors or bachelorettes over the course of 30 mins.
