Yes, the idea is great! And yes, it's a lot of work; but that's not a show-stopper :-)
We had a similar idea in discussion some month ago, but right now -i think- nobody is working on it. The idea came up in the context of the "All under one umbrella"-project [1].
@Pavol/@Boosters: Do you know if there is something going on in this direction?
In general, I would not replace the default landing-page (
http://www.opensuse.org) with such a portal. But I think it would be cool for loged-in users. So they would have there own "dashboard". This would be a benefit.
It should be possible to contribute own widgets ... and/or hijack igoogle widgets. That would be pretty social-communityish, wouldn't it?
Is somebody volunteering to make a proposal?
