Looking at how to extract data from Google Analytics, there is now a data export API available.  Although this is still in beta, with Google, what isn't?!

The basic idea is that you split your results according to Dimensions and Metrics; where Dimension supplies the cross-tabulated groupings.  For example, you can analyse your page views by country.

This is all good, until you see how to access it.  There is no official .NET wrapper for this, although there is some code available on Google Code - http://code.google.com/p/google-gdata/source/browse/#svn/trunk/clients/cs/samples%3Fstate%3Dclosed 

Still to test this stuff out though, but will post back the details when I do.

For you propellerheads, there's nothing stopping you from making direct HTTP GET/POST requests.

I've been looking at developing Facebook applications recently, and came across this podcast from Scott Hanselman.

In it, he speaks to Mel Sampat, who has created a great application which synchronises your Facebook Friends with your Outlook Contacts, pulling down the Profile Photo.  You can then sync this with your phone (or Outlook->Google->iPhone) so you have a decent photo contacts book.
