I guess GayGeek has listed all the most important things.

Since I'm focussing mainly on offering my visitors daily updates and information about paysites, I put most work in sites that offer regular updates on content and site changes.

While I still list sites with just tour pages and no further information for potential customers and affiliates, I don't put much work in promoting them. My time is better spent on sites that work with affiliates and offer a reasonable amount of promo material and update information.

After all, if a site doesn't offer update info, you never never know if you are already riding a dead horse for over six months or so, wasting your time and traffic. Seen that happen more than once.
