It appears that Google Trends stopped back in November 2006. Did I miss something? The about page doesn’t have any mention of this, only stating that:

We’ll aim to update the information provided by Google Trends monthly.

There has been some discussion about this on the Google Trends group list, but no responses from Google. I’ve emailed labs+trends@google.com asking what happened.

Perhaps Matt Cutts could offer some insight into what is going on.
