One other point is really to answer the question you asked Greenie - with an example - you and I know that there are quite a few link lists banned from Yahoo - myself being one of them, Hoes and others - and yet we all link to each other without caring about that, because we know that the trades we have are respected by Google (and they do have quite a bit more traffic
) and provide not only the natural linking structures we want but also do provide a good experience for our surfers (which is a heck of a lot more important than worrying about whether a free site is listed in yahoo)
