***Rule 1: You Are Not the Most Important Person In the World.

Naming the readme file "Readme" sort of assumes that it's the only file I'm going to have with that name, doesn't it?  Now, while I like your stuff (otherwise I wouldn't have bought it and downloaded it), that doesn't mean that you're the only person in the world whose product I'm going to buy, and as such, so that your Readme isn't overwritten by their Readme, wouldn't it make sense to give your Readme file, heck, your Readme folder, a name which logically connects it to the product you want me to read about?***

It is for this very reason that I stopped reading readme's entirely years ago! If it's called readme.txt or readme.doc or readme.html, it hit's the recycle bin.
