Collaborative Literature

on Posted by Rajesh J Advani
I got permission to link that funny post I mentioned earlier. So here it is.
I call that kind of writing collaborative literature. (You think maybe a few years down the line I'll get credit for coining the term?)

The idea for Celestial Conversation is partly inspired from this post, partly an article I read on Sulekha a month or so ago (that one was a little heavy, though), and a little by the first two pages of "Good Omens" by Terry Pratchett (that's all I've read of the book till now).
The rest of it is original!
