Wibble:

    Facebook have an army of "citizen journalists" numbering
    500 million and Twitter 175 million and don't employ any
    of them.

    Clearly, they are going to have to introduce a delay
    mechanism so that content can be checked before it goes
    up.

Who will check it? Just what is the current rate of tweeting? How fast does the Twitter firehose run? Does this man have any concept of scale or practicality?

If Twitter gets hobbled, something else will rise to take its place. Hmm - perhaps that's no bad thing.
