There’s one thing I’ve noticed so far after playing with Google’s Knol, the company’s so-called Wikipedia killer. Unlike Wikipedia, Knol doesn’t specify whether it wants us to write in an encyclopedic style.
You can already see the difference between articles sampled at random. The article on lung cancer is written like an encyclopedia entry, a long encyclopedia entry, while the article on toilet clogs is written like a how-to. (It is, in fact, authored by “The Family Handyman Magazine.”)
So, the lesson so far with Knol would be, “We don’t care how you contribute, just that you contribute.” I think that philosophy, carried out long enough, will result in a mess of inconsistency.
