I have a new panty feed at
http://www.panties.myfeedlist.com obviously for panty related blogs. I opened it with several used and worn panty related site blogs and now it is open to panty blogs of any nature.
I see it as a two way thing, sponsor rich panty related blogs bring traffic that can be used as possible new customers for the panty sales sites and the panty sales sites often have text rich content and higher pr that can bring traffic the other way and visits where the user is already looking to spend money or has just spent some on worn panties.
A text link back is required, I would prefer worn panty selling sites to use the text link 'Panty Sex' or 'Panty Feeds' and non panty selling sites to use the text 'Used Panties' or 'Worn Panties'...
