"h" "e" double hockey sticks

alright, you christians out there: what do you think the bible says about hell? who it's for? what's it like?

non-christians, agnostics, buddhists, hindus, etc...: does any of your faith traditions have it's own kind of "hell" doctrine/philosophy?

i have done a semi-in depth study of the subject of hell in the bible and i would like to see what you all have to say about it. i would also like to see what i can learn from non-christians from their faith tradition of "hell" if there is one... or just what do you think about "hell" and what it might be like?
