Thanks for the further explanation, Tony. Bootstrapping through social
links and then expanding through recommendations sounds like a really
strong approach.

I wouldn't say that clustering is bad per se, but I'm worried that if
you only have positive feedback the system will end up with inflexible
clusters that are mostly determined by the initial conditions.

For example, if I join the network and download a recipe for chicken
soup, I'll start making connections to other peers that share chicken
soup recipes. It will become easier for me to download similar files,
without getting any easier to download dissimilar files. So the next
file I successfully download is likely to be similar, further
reinforcing my connections to that cluster.

But chicken soup is only one of my interests. If my first download had
been a horse ebook instead, my experience of the network would have
been quite different.

Is some kind of mechanism needed to avoid that kind of path dependence?

Cheers,
Michael
