I've put a small website together with the aim of hosting analysis of the bitcoins network, similar to those already posted on this blog but with the idea being to keep it more up to date. First off is the top 100 rich list, I've back filled the data going all the way back to the first bitcoin blocks to be generated, on 3rd January 2009. Eventually I'll add more stats and tools so you can peform your own queries on the data. Keep an eye on this blog for updates.
The new site is at http://bitcoinreport.appspot.com/
