Note that "random sample" is not as trivial as all that, either - if
you have a very high ham:spam ratio in your training DB, your accuracy
will suffer (see the tests from Alex, myself and others). 

An easy example of this is those of us who are on a bunch of higher
volume python.org lists - Greg's sterling work there means that very
little spam gets through there. 

As spambayes takes over the world, this could be a larger problem.
