Triangular linking is old hat now
Yahoo has already worked it out.
Linking will change beyond all recognition within 2 years IMo. You can kiss goodbye to volume backlinks etc as Google moves into using hilltop and semantecs, along with MSN & Yahoo who are all playing with semantec relevance of links. also Block link analysis will change the way people link, or the way that link importance is measured more like.
All this link mongering will count for very little sometime in the future, as on topic relevance will be the way ahead.
