"In the wiki" or "on the wiki" [duplicate]

Should I use “in” or “on”?

What is the difference between these two phrases? Which is more common?

find something in the wiki

find something on the wiki

Solution 1:

I lean towards in the wiki, but I think that is simply because the usage is more common and has become idiomatic. Whether we look "in" or "on" a reference derives from our actions towards its physical incarnation, thus

• in the manual
• in the dictionary
• in the catalog
• in the directory

but

• on the agenda
• on the bulletin board
• on the list

However, when referring to a specific wiki, I would use on. A wiki is a type of website, and websites are almost invariably "on":

• look it up in the wiki
• look it up on Wikipedia
• look it up in Lexis
• look it up on Lexis.com
• look it up on the intranet
• featured on Yelp
• find us on Facebook

Solution 2:

It is in the wiki.

Wiki is a community edited knowledge base, in which one could find something.
