Best definition
A term to describe an individual who initially accesses Wikipedia for reference purposes, but after navigating through interesting wiki links

finds themselves minus half a day and plus a growing collection of Wikipedia windows; each spanning vastly different topics.

John: I was using Wikipedia to find info on a band I like; next thing I knew it was four hours later and I had 30 Wikipedia windows open.

Jane: You’re such a wikipedestrian.

John: This is never going to catch on.

Jane: That’s because you’re not selling it, ‘find info on a band’? Please, that sounds so fake.
