If you find a bad idiom in the code base -- i.e. building long strings by
doing s = s + newstuff inside a loop, take the time to document
this as a bad thing, and what they should do instead (make a list and
join it all into a string, once, when the loop is done) and stick that 
someplace, like a README other people will read before they start 
learning bad habits.

Make profiling easy. Many people prefer to be 'correct by first principles'
rather than 'correct by experimental confirmation' but  there is nothing
like actually running the profiler to find out if the think that ought
to be making the code slow really is the problem.
