If you are interested in conflicts or edit wars on Wikipedia there is a must-read article that I found last time.
Authors analysed edits made on Wikipedia and they tried to identify those articles which are likely to create “conflicts” among editor. For example when there is a controversial issue described in the article editors will probably remove or rewrite some sections. Finding such heavy edited articles can identify “controversial” issues in given language/country without actually analysing text. The fact that this method is language independent makes it perfect for comparing social attitudes on certain subjects. I wish there were more examples attached to this work.
Again, very inspiring work. I have something similar on my mind.
