GNOME Online Desktop
This basically looks like a nice idea, going forward to really integrate desktop functionality with web based apps. However it feels somewhat backwards, with the desktop developers implementing lots of connectors to various web applications. Shouldn’t it be the other way around?
What I’d envision is a desktop that tightly integrates with the web browser and provides a set of hooks for web applications to integrate with, something like a one-click installation of a small plugin that augments the desktop with functionality related to the web app.
My guess is that even if the desktop fails to deliver such integration, the web applications will, sooner or later. Google already has all the right APIs in place, it’s just lacking a proper model to share some information with some applications without exposing your whole online life to some foreign app (giving away your GMail username/password is not an option). So the question isn’t whether this tight integration over services is happening, but rather whether the desktop will be part of it.
