Let me tell you: the site like
http://www.mytextfile.com/[
^] would be
totally useless. How can you imagine a person who would want to use it? Someone who has no text editor in its system, but does have a Web browser. Where can you get such a user? I believe, only in a fantasy, pretty poor fantasy :-).
I would advise to spend your valuable time for something useful.
