Does OpenOffice have 11 million active U.S. users?
While Microsoft Office is actively used by roughly 50 percent of U.S. Internet users, according to a 2,400-strong survey administered by ClickStream Technologies, 5 percent of U.S. Web users also actively use the open-source productivity suite OpenOffice.org.
Importantly, ClickStream wasn't measuring installations. It was measuring use. The company actually installed client-side software that tracked which applications the users were running. To have OpenOffice in use across 5 percent of U.S. Internet users is pretty amazing.
