Comment:

 Replying to [ticket:4147 arma]:
 > If we tell people to use e.g. VisiTor to see how many of their web hits
 are from Tor, the visitor scripts only look at descriptors and the
 consensus documents.

 Actually, VisiTor ''only'' looks at exit lists, not at consensuses or
 descriptors:

 > Karsten has been working on integrating the tordnsel output with the
 Exonerator output. How much error is there if you only look at the
 addresses in the normal directory documents? That is, how much should we
 care about making sure to keep the tordnsel (or soon, torbel) output
 integrated?

 > By fraction I probably mean 'fraction by exit capacity'.

 Sounds like a fun analysis.  If someone wants to do it and needs help with
 the data, let me know.  Or maybe I'll just do it myself...
