Quest Categories & Languages

I think it would be really great if there were a simple categorization method of quests.... very simple and very basic, that would help me navigate through the quests. This would also allow there to be a homepage for each of those so I could see "more" new quests that were relevant to things I am interested in or know about over things that don't appeal to me. It would be super nice if a quest could belong in multiple categories.

I was thinking something really general like "Technology", "Entertainment", "Religion", "Work", etc.

Second, maybe allowing us to pick the languages we speak/understand in our profile and marking the quests appropriately so that I default to see quests that are in my languages (there could be a checkbox on the search to show all".

What do you think?
