I guess I should make some comments about these, considering I made them.. :)

Before anyone sends me any feedback, please keep in mind, whats posted here is my proof of concept. Infact, if you look at the second graph, you notice its datasource is labeled "yeah.stat". That should indicate the half-assed mannor in which they came together. I must admit, I hope these don't make it out to a large audience (just watch, this is what gets us Slashdotted), because they are not up to my standards. I know, I know.. Release early, release often.. I heard you Eric..

I'm working on a new version of my graphing scripts that will do a number of things these didn't, such as using colors to convey link properties and topic information. I'm backed up with a bunch of work, so it may take a while.

There is one minor error in Decius's description. This graph does not take topics into account at all. I threw out all that information when generating these. The links do convey direction, so thats why some nodes have two links between them. If I wasn't throwing out topic information, there would be a number of nodes with over 6 links connecting them. [Update: Little unclear here. The dot graph dosen't take into account topics, other one does. My error..]

Expect the next set of graphs to look very different.

I would like to see people discuss the privacy ramifications of these graphs, as they see them. Since these graphs are generated using the most private of information, users reputation tables, I would like to see a discussion about this. Everyone involved with MemeStreams can easily be described as a "privacy zealot", so we are concerned, and we are listening.

In particular.. In this format, when private information is aggerated, does it become statistical information that can be desiminated without infringing on user's privacy? And can anyone think of a way that an individual user's reputation information could be mined from this graph?
