Web rings are an interesting phenomena.
I started putting all of my web rings on the main page of my site until it started getting a little crowded. Then I started putting specialized web rings, such as Astronomy rings and racing rings on the appropriate pages in my site. I noticed that people were leaving my page to go to other sites who don't even display the rings on their pages. I have also decided no more than one web ring on any page except for this one. I enjoy randomly surfing the webrings and visiting the sites that all share a particular interest.
