I suppose you mean bind a bunch of items more tightly than through commonly used tags. Virtual inlinks/outlinks are more fine-grained than commonly used tags for grouping and there is no need to invent new tags (and remember what they mean). Incidentally, a potential problem with virtual inlinks/outlinks is that many users may not know when to use an inlink and when to use an outlink. So maybe supplying "related links" might be good enough. But I think the potential of virtual links to improve personalized recommendations in a way that leverages the collective intelligence of users (rather than by using more sophisticated collaborative filtering algorithms) is interesting. Also, I have doubts about personalization methods that depend on similarities among users (e.g., collaborative filtering, social networks, etc.). The method I proposed does not assume that other people share your interests along multiple dimensions. It's more fine-grained.
