Cool. What URLs have you been looking at -- root URLs or particular ads,

You're testing all known exits, right? And they're ranked in the plot by
loading time, right? But in that case, I don't understand the zero
weights in the center.
I'm guessing that Tor clients don't pick at least some of the
non-responding ones. I'd also like a cite to the selection algorithm.
Also, how are you measuring load times? Are you getting full pages with
images etc, or just the HTML?

I'd appreciate more explanation of this observation.

What I'm wondering is whether Craigslist's distributed design and load
balancing methods are slowing down access via Tor, but not intentionally.
