I'm doing a trial run with a tool called Linky List. You can enter a bit of text and a link to follow. Its purpose is for creating blog hops and such. I'm not sure about it, so just go enter something and a link and help me figure out if it's worth $24/year to use.
As I understand it, you can specify how long the link list is active (which works for blog hops). They've also got various templates if you want to mess with it yourself. You get a one-month free trial to see if it's useful.
So Linky away over there >>>>>> on the sidebar.
