Great idea, I'm keeping my fingers crossed for this initiative.
I believe that the main challenge would be to get more traction and build a community. Hope you find a way to encourage as many people as possible to join the website.
My very minor nitpick -- I would add some kind of background colour to the main post list, something like #FAFAFA looks fine to me.
Yes, absolutely! The guidelines for now are basically "same as HN, but Euro-centric content please" :) I'll write these down somewhere explicitly soon.
