I have implemented Google Analytics on a couple of websites that I run just to try it out. My impressions so far -- it seems have a very useful set of information available and some nice interactive flash based displays.
But it is so damn slow! The web interface is so slow it is almost impossible to work with. The update of information seems at least 24 hours or more out of date.
If they can get their act together and speed this thing up it could be very useful.
