A number of readers have reported that go.goadvs.com sometimes redirect readers from the blog to its ads.  If you go "back" on your browser you can usually clear it quickly.   I've notified Typepad, and we'll see what we can do to fix this in the next day or two.  My apologies for these interruptions, and thanks to the several readers who flagged it.  (It happened to me once too!) 

Also, I'm opening comments for readers with suggestions about how to stop this.

UPDATE:  Per advice from the Typepad "help" team, I've removed the remnants of the "Site Meter" widget, which stopped functioning properly ages ago anyway.  But they think it is the culprit.  We'll see.
