Here’s what we think the Editor Trends Study tells us: Between 2005 and 2007, newbies started having real trouble successfully joining the Wikimedia community. Before 2005 in the English Wikipedia, nearly 40% of new editors would still be active a year after their first edit. After 2007, only about 12-15% of new editors were still active a year after their first edit. Post-2007, lots of people were still trying to become Wikipedia editors. What had changed, though, is that they were increasingly failing to integrate into the Wikipedia community, and failing increasingly quickly. The Wikimedia community had become too hard to penetrate. - The Wikimedia Strategy March 2011 Update discusses wikipedia's declining ability to retain new editors.
