Using a wiki to write a thesis
An interesting example of using a wiki to write a masters thesis is described in Useful Chemistry: Thesis on Wiki Interest. The thesis can be found at http://usefulchem.wikispaces.com/Alicia+Holsey
There are links in the posting to examples of a theses being written via blogs and discussions on whether this would be considered prepublication should the author wish to subsequently submit a paper based on the thesis to a journal.
