WebKit Nightly currently gets 92, so this is getting better. I find it interesting how Apple is releasing the newer WebKit builds more often. I think they are trying to become an even bigger player in the web arena (Safari being the most standards-compliant browser out there (at least, as far as I'm aware) already puts them as a big player, and the iPhone sure helps as well...).
I think we could possibly see a Safari 3.2 some time soon as well; now that would be a great thing for Apple to boast about; a browser which gets 100 on the acid3 test
Hopefully blogger will get their act together by then and fix up their website to make it standards compliant.
