Emira linked to it yesterday, but it’s interesting, so I am too:
There’s a two part series over at Salon about the history, practices, issues surround E/X/Ecstasy. It’s well worth reading if you’ve used, or have ever thought about experimenting with E (and if you haven’t, I highly recommend that you, even if just once, just to really learn something about yourself & those around you whom you choose to share the experience with).
