We weren't the first to come up with the idea of making a directory of the best porn sites. I would have to acknowledge that others got there first including the reputable PornDude. Of course once he showed the way many others followed with everyone having slightly different idea about how to present the information you want to know - namely which porn websites are worth visiting or joining.
One such site which has been gaining popularity is MrPornLive. What he has gone for is a simple layout with not too many categories so that things don't end up getting confusing. There are all the usual ones plus some unusual, like Porn Games and Sex Shops, if you want to know the best place to buy toys.
If you look on the top menu though, you'll see an icon which takes you to the One Dollar Porn page. This one's probably the most useful out of all the pages I could find. It lists premium porn sites you can join for the super low bargain price of one US dollar.
This is where porn directories such as MrPornLive and ourselves come into their own. Finding out the useful info about porn sites so you don't have to waste time doing the research yourself. With a decent set of categories and a full list of links maybe you should bookmark MrPornLive - after you have bookmarked us of course.
