 whether we like it or not, it should not be in release versions of Tor.

 Well, the goal here is to get a sense of what Tor is actually used for, to
 help us understand how to focus our development energy. Think of it like
 profiling. With the additional challenge of course that, like everything
 else to do with Tor, there are privacy questions to answer too.

 As for whether to put it in release versions of Tor, I think step one is
 to get some simple code that measures some stuff, and then see if it
 works, and then see if we think getting those numbers from more relays
 would be useful and not harmful. A lot of the interesting profiling work
 will come from changes in trends over time, not from grabbing one number
 on a Sunday in September. For example, it sure would have been useful to
 have some hidden-service related broad network statistics when the botnet
 showed up in August 2013 -- and we still have no idea whether those bots
 are loading down the network right now or not.

 I do have hopes of eventually, once we've gotten everything the way we
 want it, adding some global statistics to the extra-info descriptor, to go
 with all the other statistics we already collect at relays.
