Very, very good idea. I have been looking for away to get more into asian cultures. I have traveled a lot to other places but only have so much time and it is hard to get insight into the lives and minds of other cultures from far away, esp the younger people.
So this is a good place to start.
Obviously it is very reddit-inspired, both idea and design. Reddit wasn't the first aggregator though and they are here to stay in one form or the other so that's fine and I really like the design but it is a little bit to reddit-ish perhaps, looks like a clone.
Overall grade: Nice work man!
