Vectored Signatures

It's partly a technological problem and I really like this approach to that side. (one missing item would be nulls or no-opinion on one or more dimension)

The other more pervasive problem is the business problem if you will. So much value is in the first bit of the edge of the graph, that getting incremental bits onto each such edge is diminishing returns. Especially in venture land, the name of the game is mindlessly adding nodes and edges. It is rational for the graph owner because that's the way to grow value fastest, and because more dimensions or bits on each edge makes it all a lot harder for humans (think ad buyers) to grok.

A related issue is that from a human factors / psych perspective, recruiting for 1-bit likes / friendless / petition signature is much easier.

But critics, curmudgeon, creditors, and any number of others might point out that the ephemeral popularity contest of the graph of 1-bit edges is not a good representation of reality.

Presently the solution is "graph analytics" and trying retrospectively to bolt on additional info by inferring it from the graph rather than rich edges.

As a geek I love the idea of making our edges richer but as an investor I am skeptical it is something we'll ever see outside of carefully curated walled gardens / communities of devotees.
