The ancestors of the Internet were kind enough to give us a communication standard which is free, transparent, and standardized. It would be a shame to see the tech communication landscape move further and further into the world of locked gardens and proprietary schemas.
A fun history of one of the most ubiquitous communication mechanisms ever.
I love email. It's easy, lightweight, and encapsulates a universal-ness that has never been surpassed. Having all that means I can live with the parts that suck (e.g. spam and encryption). It's fun and popular to hate on email, but I have years of messages living in a directory of simple text files, forever accessible and all mine.
