Some time back a student pointed me at this great study of the use of wikis in education:
Grant, L. (2009). ‘I DON’T CARE DO UR OWN PAGE!’ A case study of using wikis for collaborative work in a UK secondary school. Learning, Media and Technology, 34(2), 105-117.
Although students in higher education have subtler and more passively aggressive ways of staking their claims to online space and contributions, the problem remains the same - it's mine, hands off! And there is exactly the safe problem in the research community.
And that, dear readers, is the problem with wikis, and why everyone hates them.
