WordPress just support Gears (http://code.google.com/apis/gears/), the Google web local storage, into their blogs administration pages.
Gears use a little local database for store the web information that the website save inside. Google publised the first preview a year ago. Now some Google apps use it, like Google Reader, Google Docs, etc. (only english versions). An third pages’re begining to enable Gears in their sites, like WordPress or MySpace.
Could Gears suppose a web revolution? Web 3.0? What is the Microsoft response?
I think that Silverlight is a good response of the Adobe and Google attacks. Some days ago, we could read that Google now can search into Flash files. Silverlight includes offline storage, for example. I vote to Silverlight ;).
