I hadn't realized, until I looked there just now to check a Miles O'Brien update on "space news" for something I am writing, that the very promising-seeming site True/Slant has closed down this weekend. Goodbye note here. Misc press observations about the closure (after acquisition by Forbes) here and here. Initial vision here.
I don't have time to do more than note this passing, with regret. I argued in my recent "Google and the News" article that the years ahead for the journalism biz will amount to "experiment, experiment, experiment" -- figuring out what will work as a new business model by exploring all possibilities and learning, as quickly as possible, what doesn't work. (This is known as the "fail fast" principle in the tech world.) Sorry that True/Slant will go down as an illustration of what didn't work, rather than what did.
