In the early days of Wikipedia, people wondered whether the quality of its information was as good as that found in encyclopedias (remember those?). These days, Wikipedia has gone completely mainstream. Its entries are often provided right alongside Google search results. Thousands of sites borrow the data and display it as fact. Wikipedia is the Internet’s sixth most visited site. But did we ever answer our original question? Is the data good? And is there a chance that it’s not as good now as it was a few years ago? Consider this: Wikipedia’s volunteer workforce has shrunk by more than a third in the last six years. “When Wikipedians achieved their most impressive feat of leaderless collective organization, they unwittingly set in motion the decline in participation that troubles their project today.” From Tim Simonite in the MIT Technology Review: The Decline of Wikipedia.
