“Knol is short for “unit of knowledge” and
anyone can create their own knol. If there is one thing which
characterises the free software model it is that it is
collaborative, whether it is a wiki, a distribution or the
development of a piece of software—or Wikipedia. Of course
there is nothing to stop you acting as a one man band, but
knowledge is often advanced and improved when the effort is
voluntary and collective. There the resemblance with any kind of
Wikipedia-killer ends. Knols are individual creations and the
creator of a knol retains ownership of their creations and controls
any moderation.”
