Let‘s say I mention in my write-up an avant-garde jazz pianist. How this should be hardlinked?

1. avant-garde jazz pianist – that is, one link
2. avant-garde jazz pianist or avant-garde jazz pianist – two links
3. avant-garde jazz pianist – three independent links

The third option is most generic – the reader is invited to see what do people over E2 think about each of these terms: avant-garde, jazz and pianist. Yet, it is perhaps too generic. It‘s advantage is that it presupposes least of reader‘s knowledge.
The second option is more interesting. Yet, the decision must be made – what is more important, avant-garde jazz or jazz pianist? That is, does the reader knows (or better yet, is interested in) what jazz pianist is, and thus would rather read about avant-garde jazz, or has some notion of avant-garde jazz and is more interested in jazz pianists?
The first option is most concrete, and leaves little for the reader to decide.

Assuming that all of those nodes really exist, the probability of getting some useful information is higher for the shorter (one or two word) links than for the cluster.
But the decision must be made. In the end, you think about your ideal reader and choose one option. It affects the way people move around E2 greatly. Of course, they can search by themselves – they‘re not limited to the explicit links, but is their attention focused enough? After all, we‘re just surfing...
