= PageRank-like ranking
{c}
It would be really cool to have a <PageRank>-link algorithm that answers the key questions:
* what is the best content for subject X.
For example, if you are reading `cirosantilli/riemann-integral` and it is crap, you would be able to click the button
> Versions by other authors
which leads you to the URL: http://ourbigbook.com/subject/mathematics[]. This URL then contains a list of all pages people have written about the subject `mathematics`, sorted by some algorithm, containing for example:
* http://ourbigbook.com/johnsmith/riemann-integral
* http://ourbigbook.com/cirosantilli/riemann-integral
This URL would also contain a list of issues/comments that are related to the subject.
* who knows the most about subject X. This can be found by visiting: http://ourbigbook.com/users/mathematics[] "Top Mathematics users", which would contain the list of users sorted by the algorithm:
* http://ourbigbook.com/johnsmith
* http://ourbigbook.com/cirosantilli
However, Ciro has decided to leave this for phase two <action plan>, because it is impossible to tune such an algorithm if you have no users or test data.
Perhaps it is also worth looking into <ExpertRank>, they appear to do some kind of "expert in this area", but with <clustering> (unlike us, where the clustering would be more explicit).
