Some time ago I started a wiki called "norske kaffebarer" aimed at describing all the best coffee bars in norway. The work ground to a halt for several reasons, but maybe mostly because the wiki software I installed wasn't very user friendly. I've bought some server space now and switched to the same wiki software that is used by wikipedia.
I've also renamed it "norwegian coffee bars" and aim to do it all in english so that it is useful to as many coffeegeeks as possible.
