In view of my lack of success with domain parking services, I've started to set up a variety of mini-sites for some of my names. I created a URL shortening site to help me with posting links. One of the options on this site is to insert an interstitial in the link. I wondered if it was worth doing this to indicate that the name may be for sale, and to link to a purchase facilitation site. Has anyone tried this, or maybe used a popup as an alternative?
