Does having a lot of reciprocal links on one page hurt your rankings? When I first started my site, I was just submitting it to various directories and didn't care that a lot of them had the recip link requirement. More recently, I would only submit my site to non-reciprocal directories.
a link is a link, best way to link is a - b -c linking directories will let you do this as when the script checks for the recip link they dont know which domain its comming from.
