Wikipedia celebrates its tenth anniversary on January 15. Everyone knows that Wikipedia is a great source for research and browsing, and one of the most spectacular examples of success in the field of community-generated content. What’s not always obvious are the social benefits you can derive from actually being a contributor to it, as I learned during a rather odd edit war with an ill-mannered Nolans fan a couple of years ago.
Open-source mapping tool Crowdmap creates interactive maps for visualising location-based data on a map and timeline. The tool crowdsources information via a web form, mobile phone or Twitter, though it also uses news sources to document and verify incidents.

Drawing on the enthusiasm of crowds is critical to the success of open source projects. However, Wikipedia founder Jimmy Wales — no stranger to the virtues of collaborative enterprises — reminds us that there are limits to how far this can be taken.
