Have you ever given plain text some thought? I mean the stuff that you get when you use a simple text editor like vi or notepad2. Initially, plain text looks boring, especially when you compare it to some of the things you get when using OpenOffice.org or Microsoft Word or whatever those monster programs are all called.

Plain text is powerful. It is easily searched, it is portable across platforms, it is easy processed by programs, it can be converted to look nicely (this site is powered by plain text) , and it can be massaged into other formats.
