I was discussing with Tyler what other websites I would consider setting up, if i didnt do the love and relationships one.. .

I would have considered a humour/comedy/funny/giggles type site, with jokes, funny lists, that sort of stuff. Not so much because i believe it to be hugely profitable, but just because when to get people to a site like that, they are very likely to check out the other articles too, and once you have them looking at multiple articles, its easy to get them returning to the site, and its therefore easy to get them to click on advertising, since good advertising looks like more articles :-). It would also be a subject that would encourage people to "link to this" on facebook and their own blogs and stuff like that.
