Za3tar has created these awesome blog readership graphs by using a script which generates how blogs link and are linked to on Qwaider Planet. He has even made one especially for ChocolateMintsinaJar (so cool).
It is interesting to see how these blogs are connected. Like any community, some blogs are more active and connected than others. It would also be interesting to see how these relationships change with time in terms of connectivity and in the strength of this relationship.
