Wikipedia may be going dark within the hour in protest of SOPA/PIPA but that doesn't mean it's going offline completely. With very little work, you'll be able to access the online encyclopedia tomorrow—even if that does mean going against the entire spirit of the protest.
According to the Wall Street Journal, a Wikimedia spokesman confirmed today that the mobile version of the website will remain online at en.m.wikipedia.org. Also, any API that pulls information from the Wikipedia servers will remain active as well. That means you'll also still be able to access Wiki content through Facebook. [WSJ]
