Writing on Reuters, Felix Salmon has a good postmortem on the demise of the Daily, Rupert Murdoch's iPad-only, $30,000,000 subscription-based newspaper, which folded yesterday. Among other things, he writes about print media's enthusiasm for iPads, and the inability of closed ecosystems to out-iterate the open Web:

When the iPad was first announced, there were lots of dreams about what it could achieve, and how rich its content could be. But in hindsight, it’s notable how many of the dreamers came from the world of print. Web people tended to be much less excited about the iPad than print people were, maybe because they knew they already had something better. The web, for instance, doesn’t need to traffic in discrete “issues” — if you subscribe to the New York Times, you can read any story you like, going back decades. Whereas if you subscribe to a publication on a tablet, you can read only one issue at a time...

Similarly, when the iPad launched, it allowed people to do things they could never do with a print publication: watch videos, say. But at the same time the experience was still inferior to what you could get on the web, which iterates and improves incrementally every day. The iPad then stayed still — the technology behind iPad publications is basically the same as it was two years ago — even as the web, in its manner, predictably got better and better.

I was skeptical of the iPad for this reason from the start:

I think that the press has been all over the iPad because Apple puts on a good show, and because everyone in journalism-land is looking for a daddy figure who'll promise them that their audience will go back to paying for their stuff. The reason people have stopped paying for a lot of "content" isn't just that they can get it for free, though: it's that they can get lots of competing stuff for free, too. The open platform has allowed for an explosion of new material, some of it rough-hewn, some of it slick as the pros, most of it targetted more narrowly than the old media ever managed.

Cloacina was the ancient Roman goddess of sewers. Think about that for a minute. To the Romans, the ability to take vile, disgusting wastewater and just get it the heck out of Rome was such a miraculous feat that they created a whole deity to watch over and protect the pipeline.

Now, how much more impressive would Cloacina have been if she could turn the sludge into usable water again?

Today, cities around the world are shifting away from the historical focus of wastewater management (i.e. the miracle of making the wastewater go away somewhere where we can't see it) and adopting a new paradigm of re-use. David Sedlak, professor of civil and environmental engineering at UC Berkeley, studies wastewater and spoke about water recycling at the 2009 Nobel Conference on water conservation issues at Minnesota's Gustavus Adolphus University. He said that people are often turned off by the idea of cycling water from the toilet to the tap and back again, but water recycling is very different from simply filling a glass out of the John.

In fact, you could be drinking recycled water and not even know it.
