I think I could also download the csv file and parse that to get whatever
data I wanted.

It really depends on what statistics I cared about (e.g. there are less
than 4000 bugs while there are less than 25,000 closed bugs). If I just did
high-level statistics it wouldn't be bad, but if I try to track every issue
independently that might be annoying (and actually cost money for me,
although I already personally pay for py3ksupport.appspot.com so I can
probably piggyback off of that app's quota). We will see if this ever goes
anywhere. =)
