Generally speaking, I would consider Warren Ellis to be the rabid dog of contemporary literature. He lives entirely by means of red bull, GOOD whisky, cigarettes, and a signed contract from the devil granting him complete immunity from death so long as Ellis doesn't let lucifer's missus know about the mistress he lets dress him up as a piece of asparagus and then trim him in ways that would make bmezine blush (I'm sure Warren tells her anyway, because he's just that kind of bastard). He's made his living, from what I know, mostly as a comics writer with a style that could probably be best described by taking Alan Moore's misanthropy of the 80's, turning it inside out as a hat, dousing it with gasoline, then running screaming naked down the streets of london with it ablaze in a whiskey induced haze that would have made Ernest Hemingway recommend him for rehab - by which I mean he would have called the cops to come restrain him down and put him a way in a padded room until judgement day with priests of all denominations around guarding to make sure that nothing ever came back out.
An early adopter of social media, warren ellis carved a niche among many of us by being out there on a daily basis, emailing, blogging, and now twittering -creating a connection with his audience that many now cite as their reason for psychotic break. Trademark of this was his introduction "Good Morning, sinners." In twitter, he has found some variance, a thing which now proves to be his downfall - the creation of a Warren Ellis simulator that is so spot on people now ask him if he's ever heard of it, or even worse yet, if that's where he gets his insults from. As someone who's been enduring Warren's derogatory remarks about everything for a few years now, I can certainly say that it is truly a third order simulacra. It is mechanical, algorithmic, and reproduces the bile which spews forth from the damnedable man in a way that only serves to infuriate him further. I present it to you now:

We can only hope the apocalypse will come before the website "http://talkliketalklikewarrenellisdotcom.com" is created, otherwise I'm sure the man himself will do much worse.
For other instances of his work you can find him (or some of the things he does) here:

Post Script: If anyone is offended by the tone or content above, just know that Warren would have made things much worse.
