email. It's a nice simple thing. It's all nice plain text. You send it to someone and regardless of their mail client they can read it. Or at least that's the theory. It's certainly the beauty of it.

Of course that simply isn't good enough for people. First they said that plain text wasn't expressive enough. They needed different colours and typefaces. They needed to embed images and have coloured backgrounds. They needed mail clients that could create and read emails formatted in HTML.

And then there was the problem that once they sent an email the recipients had a copy available to them for all eternity. Surely that can't be a good thing with something as easy and quick to send as an email. Surely something could be done? It could.

We've come a long way.
