To this day I don't think we talk about the localization story in ASP.NET 2.0 enough -- the built in framework really makes it simple to produce a multi-lingual site, the type of thing that would take TONS of code and pain before.  In October we released an article that discusses the system in depth -- we updated it today to be inline with RTM and have 3 supplemental papers in the pipeline to continue teaching folks about localization.  If you care about localization at all this is a must read -- Expect 1 article every 3-4 weeks on this topic from us, i'll keep you up to date here.
