What kind of a thing is Krishna?

(Commenting here since the text doesn't seem to appear with the URL)

I am a Hindu (but an atheist). I was reading a bit too much Vedanta recently and thought it might be interesting to give an atheistic twist to the idea of Krishna. People waste a lot of time on Krishna in India - why do they do so? What is the attraction in what is clearly a character in an epic/purana? That was the question I wanted to answer.

It's supposed to be a fun read. I am not scholastic or anything!
