Have you ever used an online dating site? Have you met someone that way?
One of the most popular (and free) online dating sites is Plenty of Fish (
www.pof.com). I've been on there a few times and made a few chat friends that way but never anything serious as I wasn't "looking". Traffic-wise, POF is phenomenal.. Markus (the owner) operates it pretty much out of his apartment and grosses over $30k a month in ad revenue! Goes to show how profitable even free online dating can be!
Always seeing tv commercials for sites like eHarmony.. I suppose if you meet someone, even a paid membership could be worth the price.
I met my last girlfriend online in a chatroom.. neither of us were looking for anyone (she'd just divorced) yet we ended up together 4 years and still stay in touch today..
