"Going down a wikihole" is a term used to describe the phenomenon in which one opens a wiki article about
something cool, clicks on a link to another article about something ever cooler, and eventually comes up for air 6 hours or so later after having clicked on all manner of related cool wiki links. The word is based on "wiki" as in "wikipedia" plus "
hole" as in rabbit
hole, and is inspired by the notion that wikipedia offers its own highly seductive type of single-user rabbit
hole. It is similar in meaning to "wikitrail" but implies a certain loss of control at some point.
