WHATWG, RIAs and online/offline applications

TechCrunch has a really useful survey of the current status of browser storage, what it really means, how it relates to WHATWG's work on HTML5, [Google] Gears and current and forthcoming browsers. It's explained a lot to me and given me at least the idea that WHATWG's work is coming to something. Looks like we can't yet know quite how the RIA technologies like AIR, Silverlight etc will tie in with this, but the article ends on a very optimistic note about being able to programme to one API since the only mature product (Gears) should be fully HTML5 compliant. All good.
