If you're looking for interesting, witty commentary on the news (with a majority US slant) then I'd like to strongly recommend a new blog on the block called The Crossed Pond. It's run by three miscreants I have known for nearly a decade, one Brit, two Seppos.
All three are superb writers, although bizarrely I've just learnt one of them has gone from being a card carrying member of the Libertarian Party to voting for John Kerry. Anyways, well worth a look and guaranteed to be regularly updated.
