It's in the same general department as the blogs-are-ruining-the-world riff. Andrew Keen 'believes that "web 2.0" is killing our culture'. Yes, 'millions of exuberant monkeys are creating an endless digital forest of mediocrity'. Monkeys, geddit. An example of the problem is Wikipedia. It's 'full of mistakes, half truths and misunderstandings'.
These are all laments you'll find here.
To which I say:
1. Books that you read can contain mistakes, half truths and misunderstandings.
2. Newspapers that you read can contain mistakes, half truths and misunderstandings.
3. Even teachers sometimes get things wrong.
4. If you are misled by something you read, hear or are taught, someone or something else might just put you straight sooner or later.
5. You can find many things out in a quick and handy way from Wikipedia.
6. If you're careful you can check them against other sources.
7. Not everything you learn on Wikipedia is mistaken.
8. The claim that it's killing our culture is silly.
