Help me to sort niches the smart way
 

Hello guys, i own social porn site - PickyPorn.com
As you see, there's a lot of top level categories - asian, anal, gay etc.

I think it would be a good idea to extend this list and put those categories into 5-6 higher (top level) categories. So, here's the question: How'd you separate categories? Which top-level categories you'd create? If you know good example with not so much top-level categories (i'd like to have no more than 7), please advice.

Thank you in advance!

Nice digg clone, running several social bookmarking type sites as well and I prefer letting submitters tag the sites and have no categories at all.

If you don't have loads of time and links to fill it yourself, you'll end up with overcrowded common categories like tits, anal, milf and many totally empty categories. Not necessarily bad, but categories don't really encourage submitter to spend some time on creative tagging.

Looking at my sites, those without categories get alot more traffic, since submitters use more specific and targetted tags instead, making it grow naturally by what surfers are looking for.

Get rid of the torrent links, noone likes torrent sites and it looks like "torrent" is your top tag...why lure visitors on sites where they can get everything for free ?
