For general principle, I always thought it was a little strange that Tor 
changed circuits every 10 minutes.
That it was too predictable, like a patrol car driving by the bank 
exactly at the beginning of the hour.
Never deviating.

There may not be any current, known exploits of this in Tor, but many 
things in Tor are built around randomness - for a specific reason.

On the other hand, what about destination sites that have only a few 
active Tor users at a given time.
Of course, their 10 minute circuits wouldn't have all begun at the same 
time.

But of the Tor users on that site, if only one users circuits change at 
a specific time & continue to do so every 10 minutes, does that make 
them harder or easier to pick out of that specific crowd?
