Community intelligence
• Traditional media revolves around the Short Head – a few number of publishers putting out lots of content

“Wikipedia
• Wiki: “… a website that allows the visitors themselves to easily add, remove, and otherwise edit and change available content, typically without the need for registration.”
• Wikipedia: “the free encyclopedia that anyone can edit.”
An expert-led investigation carried out by Nature … revealed numerous errors in both encyclopaedias, but among 42 entries tested, the difference in accuracy was not particularly great: the average science entry in Wikipedia contained around four inaccuracies; Britannica, about three.

• The Gene Wiki is complementary to, and not in competition with, existing gene portals
• Users must be aware of the advantages and disadvantages of the Gene Wiki’s open editing model
• Other community intelligence models are valuable and are being explored
