I see no performance problem by adding this. Remember though that we
want to cache those redirects so the Python code will not be executed
for every request. Those won't be real stats.
My biggest concern about our redirects is that we keep adding, adding,
adding and our .htaccess files are a mess because of that. We've just
started doing some redirects in Bedrock and if we don't pay attention, I
believe it'll become as messy.
We're already paying for a service with our own domain. I believe we
should use that for our vanity URLs. It provides a better stats service
and a shorter URL to type. I seem to recall Chris made a decision about
this earlier this year.
