On Using Plain Text

Give the post a read. It's worth your time.
Is plain text the best option for everything? Of course not. But for a lot of what we all do in our lives, plain text is an alternative (and antidote) to closed, proprietary file formats and services.
If you're interested in learning more about how to incorporate plain text into your life (even if you're not a techie), you should consider visiting The Plain Text Project. In case you're wondering, I maintain that site.
