I did say "starting point for a research project".... You could take it in all sorts of directions, and relate its particulars to the general issues of historiography. You wouldn't need to write 30 pages, though - just 2500 words plus 300 word synopsis and 600 annotated biblio. My experience has been that students usually need to narrow their initial topic considerably, and even then struggle to fit their research into the 2500 word limit. But I'm not advocating that anyone focus entirely on the Wikipedia situation here: you'd obviously want to relate it to other "competing narratives" and "selection and deployment of evidence" issues.
Here's a little list of (somewhat overlapping) Historiographical Issues that I have found useful for the case study and research project. I originally compiled this list as an indication of the type of topic which might form the focus of HSC Question 1 (Historiography)
