I have a PR5 website, www.hammockuniverse.com
I am interested in exchanging circle links with webmasters - In other words, I would link to 1 site, and a 2nd site (different from the one I link to) would link to my site. This sort of arrangement is much more beneficial with search engines.
This obviously applies to those webmasters who operate more then 1 site.
Also of note, I will not exchange if my link is placed in "lala land" on a website... somewhere nobody would ever find (ie. Massive hard-to-find directories). I take care to make the links on my site attractive and visible, and I would expect the same from others.
