[I]t’s doing more than subsisting, it’s thriving. Wikimedia Foundation’s annual fund drive raised $4.5 million in 2008, $8.7 million in 2009, $15 million in 2010, and now $20 million in 2011. The drive is also getting faster (dropping from 67 days to 50 from 2009-2010), and broader, as seen in the increased number of donors. Besides Wikipedia, there are ten sister projects: Wiktionary, Wikibooks, Wikimedia Commons (aka Wikicommons), Wikispecies, Wikiquote, Wikisource, Wikiversity, Wikinews, MediaWiki, Wikimedia Incubator, and Wikimedia Metawiki. Each has its own dedicated user base and corps of volunteers. WMF has sites in almost every country and in 282 different languages.
The 2011-2012 Foundation Plan calls for expanding the sites further every year. The 2011-2012 budget is actually $28.3 million, with missing funds to be met by grants from institutions like the Sloan Foundation. (This drive and grant combination is the norm, and it seemingly works well.) Wikimedia has increased its hires, bringing the company from 50 to 78 in the past fiscal year and aiming to further increase staff by as many as 35 more hires. Wikimedia Foundation has plenty of money to spend as well, they run a high level of reserves ($13 million or so), and they continue to exceed their expectations in revenue. (Revenue was up 50% or so in 2010). To balance that boon, spending is going to increase by 24% in 2012 to invest in better harnessing the crowd.
