I don't quite follow you on this comment:
I designed this other site to help people find what they are looking for. However, I trade links to raise ranks, not to provide a resource page of links—that's not my aim with the links directory though it can serve as such to the visitor if they happen to find it via a search. I just expect a fair trade off between link partners (that was my point).
In fact, if linkpop was not a factor on my page rank for my other affiliate site, I wouldn't even trade links with other sites. There would be no reason to do such a thing. But lets face it, linkpop is a factor and thus when high ranks become important, one does what one has to in order to gain higher ranks under relevant search terms. That's just plain simple logic.
That other site really has no other reason to have links except for linkpop. The site by itself has all the information it needs without the links directory. I suppose I get a trickle of traffic from link partners but not enough to really matter much.
