This is an analysis of the keys of OLS2004 attendees, last updated on 02 January 2008. You can download the key ids and the ascii-armoured keyring from here. Keys show up in the graph once they've been signed by or have signed at least one other key. Keys show up in the statistics at the bottom once they are reachable from any key in the strong set.

There's an explanation of these analyses and a FAQ by the original author.

I used sig2dot to produce a postscript and JPEG graph of this subset of the larger Web Of Trust. Due to the number of people involved, this graph is extremely large and may cause your computer to swap itself to death.

If you're interested, I have other reports available. You may wish to register yourself with Biglumber so other people in your geographical area can find you.
