Everyone has their preference, but the reason I do it is because of
maintenance. I can think of other reasons why a person may want to
filter the traffic.

1. keep weblog clean
2. reduce bandwidth usage

There are lots of ways to filter out the stuff for weblog analysis, so
writing a filter isn't necessarily easier or better. On the other hand,
if you're connection has a cap, then writing a filter will save your
bandwidth. Most production sites don't have bandwidth caps, but with
enough nimda requests, it can slow down the site performance.

everyone has different requirements, so use your own judgement as to
what makes the most sense technically and financially :)
