A sentiment I can absolutely agree with. Increasingly, it's possible to dominate results for UK-based Google audiences, with little or no international presence, and all-but invisible performance at google.com.
A related observation: 'international' search results seem to share features in common, and it seems that there is an 'international' (i.e. a regional Google TLD) element that is not applied to google.com results. And then, of course, regionalisation kicks in ;)
