As a former user of XOOPS, I think this is well-deserved.

Thanks for the PR.
According to w3techs stats XOOPS has a market share of less than 0.1%. While I agree it is a great system, we cannot add all PHP CMSs to the timeline and keep it clean and comprehensible.

This is a "php-timeline", and not "php current market share", right? :)

While we might not have the market share that we used to have, I believe that XOOPS has made significant contributions to the growth of PHP, as the number of books, awards, and articles proves.

It would be a shame if you would ignore and forgot projects that helped to make PHP to what it is today!

I agree with Michael Beck (@mambax7).
Google trends also suggests that Xoops, Drupal, Joomla, and WordPress competing with each other, and even being more mature and with a more search trends by the time.

Ayesh Karunaratne (@Ayesh), thanks for the Google trends chart, clearly showing that historically, XOOPS has made significant contributions to popularize PHP!

Ah, I see, thanks for clarification, that makes sense to me now.
