I published my end-of-year think piece, The Un-Internet, about an hour ago by posting it to my linkblog. Which, among other places, flows to Twitter. Which is down.
We're way too dependent on the Un-Internet., which behaves somewhat like the Internet, but has chokepoints that can cut off the flow. The whole point of the Internet, from the point of view of the US Govt, was that it couldn't be cut off this way.
I like to say that RSS doesn't have a fail whale.
