What was life like before we had Wikipedia as a consistent reference source? Believe it or not, people actually used real, printed encyclopedias, and even programs like Encarta. Compared to the vast network of user-sourced knowledge we have with Wikipedia, old-school programs like these seem clunky and cumbersome. Even better, Wikipedia is completely free, and devoid of any advertising influence. In an Internet that is constantly under duress by corporate powers, Wikipedia stands above the rest as a mecca of accessible and (mostly) reliable information.
