I use it too! It's just fantastic. The only thing i miss (and as i know they are working on it) is a view where i can see referral-page stats (so i can know the page the referral is linking).
Also maybe it's worth to consider using an actual database for high traffic sites, sqlite can slow down a lot.
An extra bit is disabling debug in configuration, you don't really need it in production :-)
Cheer!
