To be honest I think this is step 1, perhaps the best first step EVER MADE to move towards progress in HTML. With this plugin basically we can finally make messages on websites in the same way flash is installed to download google chrome and we have HTML5 compliance (once the spec is done and fully implemented). It will be great. Till now were stuck with HTML 4.1 until the entire world moves to IE8 AT LEAST. This is really a technological leap.
