I think the point about it being more like real life is a great one. I think the online dating industry will grow like the personal training industry. Online dating websites will become "gyms" where people do more than "look for love", they buy their love books, love profiles, love advice, how to dress, how to etc etc from one website. And of course, the sites will look more like clubs, bars or country clubs - social environments with a who's who and special announcements about someone getting engaged, etc. People need social interaction more than ever, and the online dating community is thriving to give it to them.
So the question is, how do they make money? My first thought is bake sales. So that's probably not the best answer. The industry will probably continue to break out into your more results oriented / profitable ventures, and separately, more community driven non-profit type of ventures. The profit driven ventures need to have "handles" on the results they are promising. That's where the money will show up.
I plan to be the "personal trainer" at the gym. I'm a love coach. If you want to work with me on a great new project, give me a shout. I posted on another topic "Dating Seminars" with the details for the project.
