I build websites for small business, and since the beginning have used Google Analytics. What used to be a valuable tool that I would eagerly tell my clients to utilize, has now become an overly complex nightmare I loathe to install and rarely recommend to my clients. I recently had a client ask to use StatCounter.com (my reaction: "they're still around?!?") and it was refreshingly simple, much like the original Google Analytics.
I'm sure the new GA is super powerful, but most people just want to see how many "hits" they got, what content is most popular, and where the visitors came from. Google would do well with a simplified Analytics service just for small business.
Once you go down the optimization route, if your Google Analytics isn't super valuable it's an easy bloat to eliminate.
