I've got some free time ahead of me and was thinking about some new sites. one of them is a 4 or 5 way link exchange. I'd like your input to know if it's worth the effort basic idea is a site like linkmarket.net : You have site and can put outgoing links on it (somewhere). There are more sites like these and you swap links. 1 on 1. My idea adds the following: you do not swap links directly with other members, but only with members that do not link back to you directly. you link from A to B, B links to C, C to D and finally D back to A. (or any other level (4,5,10? who knows) For every incoming link you should add one outgoing link to your site, validated every day by the site etc. What do you think? Can this be of any use, has it been done before, will you use it? let me know
