What's wrong with all those dating sites?
froo: Channeling PG for a moment: Make something people want.I think that on the whole, most dating sites are more concerned with figuring out how to make a buck off someone than what their users want.If you use Wordtrackers keyword tool which people normally use for SEO purposes and type in "dating"... 4 out of the top 10 keyword are related to free dating sites, but how many dating sites can you name that are free?I can only think of one off the top of my head (penty of fish) - and Markus is making a killing with his site. [edit: if you take the social networks like facebook and myspace into account, you have a couple more - but the traffic to those sites is less qualified, IE not people specifically looking for dates]I think that if you can build a decent site (it really doesn't have to be that fancy) that you can run free - I think you would have a better chance at success than simply trying to build more complex functionality and charge people for it.Make the site simple, make it user friendly.
