Ask HN: local "Show HN"

I like HN a lot, and I always get excited when I see “Show HN:” on the front page. But there is one thing that bothers me a bit. I think I’ve never seen any local projects.

I would like to be able to search for projects from Germany, France or even Austria (that’s where I am from). This could also be a great way to network with people near you.

So what do you think is there a need for such a site?
