More Refined Geotargetting for Adwords / Adsense

A few bloggers have picked up on a vague rumour that Adsense maybe introducing much more advanced and refined geotargetting later this year.
From a publisher’s point of view this may be good news, but from an Irish advertiser’s perspective it won’t make any difference.
More refined geotargetting may work in other countries but in the Irish market it is technically impossible unless you are interested in the very small ISP’s clients.
