New Betweenness Centrality Stats available. Lots of changes in the ranking. New shooting
star is the CaCert pubkey.
Key creation time and sigs from forgotten keys influences the ranking
All norms on key graphs have to deal with time somehow. This
is because keys are created over time, revoked, they expire, their passphrases
are forgotten … Signatures expire, point to revoked keys …
In the BC norm, this has a side-effect on newer keys:
since newer keys will never get signatures from revoked or unused
keys, they are at a serious disadvantage (sorry, weasel
If there are n keys in the component, and only one has
a link to/from an old key, then it's BC will increase by n-2
(because n-2 shortest paths lead through it to the forgotten
At the moment I see no way of repairing this.
