Webmaster Tools was recently updated with a new tool to allow specification of a geographic location to associate with your website. This will be useful to organizations whose sites server a specific area and do not wish to reach the full world wide web but want to be more relevant to specific geographic search queries. When not specified, Google continues the current practice of associating content with the top level domain (e.g. .ca) and the IP address of the server where the content was served from.
I also just took a look at the graphs of Googlebot activity in the Set crawl rate tool now that I have enough data to show graphs. It looks very clean, with the information presented in a nice, uncluttered fashion.
