What are webrings? Webrings link together sites with something in common, in this case Harley Davidsons and Motorcycles. A surfer who wants to surf sites about something he or she likes, can easily go from one site to the next in a webring, and eventually end up back at the first one in the ring.
Webrings are fantastic surfing tools, this is proven by the popularity of them. I personally love webrings. Many of my websites' hits come from them. If you have a website, you should consider joining some webrings. If you are a surfer, have fun!
