I was messing around with an old version of Encarta recently, and it got me to thinking how cool it would be to have a modern encyclopedia run locally again. This lead me to Kiwix... And the 79 GB archive of English Wikipedia.
Kiwix is a great idea for places with limited / no Internet due to infrastructure or oppressive regimes, but living in the United States in a major metropolitan area, Kiwix has little use for me.
