Seems that the Alexa column is not sorted properly? -- RadomirDopieralski

Yah; it's because it contains non-numbers, so it gets sorted as a set of strings, not as a set of numbers... -- JanneJalkanen

I turned all the Alexa ranks into numbers, even if that means it turns into non-sensical data and moved the star warning that the data is not accurate to the wiki engine column. -- ChuckSmith

Is someone regularly updating this page? Wikkawiki is not included in the list. There are currently [880000|http://www.google.com/search?q=%2Bwikka+%2Bwiki&hl=en] Google Results for Wikka (please note Wikka is often referred to as Wikka Wiki—two distinct words—hence the query I used to calculate these results: +wikka +wiki) and the domain wikkawiki.org has an Alexa traffic rank of 109,930. If no one is actively mantaining this table, I'll go on and add this entry myself -- DarioTaraborelli

Go ahead. But I think it would be fair to also update other entries then -- their ranks might have changed. -- [RadomirDopieralski]

I'm not sure what is listed in this table under "Google Rank"? Initially I thought it's the number of page hits for a string unique for given engine (like "MoinMoin Powered" in case of MoinMoin), but I just made some searches and the results are **much** lower -- I don't think they decreased so much since their collecting.

Then I thought it's just the number of page hits when just searching for the name of the wiki engine -- but again not, for example there are 144,000,000 hits for MediaWiki, while the table shows over twice this value.

Then I've gone to http://googlerankings.com/ and dicovered, that there is no way to know the rank without a key. So there is no way to update or even verify the results.

I just went to Google and typed the name of the search engine plus the word "wiki" without any quotes.  Maybe not the most scientific method, but it gives you a pretty good idea of how popular wiki engines are.
