- evgen 18y agoStrict pagerank does set global weights (necessitating the "seed" values that I mentioned in another comment), but this is not a requirement of flow-based weighting systems. If you implement a canonical pagerank algorithm then you will get a global view based upon what certain people feel is important/worthy, and as you expand the set of seed users you will end up with complete personalization. There is a continuum here and deciding where to reside within this range has some pretty large effects on the nature of the site. Google determines global pagerank because they lack the computational horsepower to do otherwise and because web pages and users are not similar entities, but on a site like this where the links between users and articles are effectively a single measurement this sort of individual pagerank is possible.
