With either approach, we would both eventually end up with all the websites - that being a surprisingly small number (~1 billion of which we only ever access ~1000).
I got in an adult content bubble from starting with "A" ("Adult") and would have hit another one presumably at "X". But "B" had quite a few too, lol.
Most of the words were bubbles - where it spent a decent amount of time on each one and I wondered if it would ever move on or was stuck. There are just a lot of backlinks and tangents for every word you can think of.
Another fun thing about this experiment is you will find a lot more international websites that no other search engine will find - some weird personal sites and some surprisingly good forums.
But yeah, you could enter anywhere - Wikipedia, or some other random Array of words. It doesn't have to be a dictionary.
