Yesterday I tried to add Google Analytics to by blog and it royally farked my ability to add posts. With .Text you can't access the HTML Head tags, and my attempts to stick the required JavaScript in other places all failed.
I did however get it on my regular HTML pages, too bad no one visits those and my blog is all I care about. :-P
I checked out the stats today though and it is pretty neat! There are several dashboards (Executive, Conversion, Marketing and Content Summaries) and some reports (Marketing and Content Optimization) as well as a Date Range control for viewing stats.
The Executive Summary includes Visits (by Source, New and Returning), Page Views and a Geo Map Overlay.
Pretty cool stuff and hey, free stats are free stats. Another free tool in case you are interested is StatCounter. And if you get Analytics working on a .Text blog, I would love to hear about it :-)
