It has been some days now, that krugle has been announced. But this could really be an interesting step towards the idea of global knowledge sharing. I haven't yet grasped, how krugle will technically do, what it promises - but it is a huge and interesting mission. Making code searchabe, annotatable and accessible to anyone - wherever that code resides or was invented. Google has gone evil since some time now - and if no free alternative arises, krugle supposably will, too! Or it will be bought by Google - which doesn't make any difference!
Never the less I'm eager to see the technology behind it and the site working. :)
