Imagine a world in which every single person on the planet is given free access to the sum of all the knowledge we as a species have gathered about cactus plants. I realize it sounds impossible, like something out of the popular writings of J.R.R. Tolkein or Dan Brown, but that’s exactly what Cactus Wiki is doing.
No, not THE Cactus Wiki–just Cactus Wiki, with no definite article. This is a common mistake for newcomers.
Cactus Wiki is a free encyclopedia about cacti (plural of cactus, also spelled “cactuses”), written collaboratively by the people who use it. A wiki is a special type of website designed to make collaboration easy. Improvements to Cactus Wiki are constantly being made by cactus experts worldwide, professional and amateur alike.
One example of an article on Cactus Wiki is Cleistocactus strausii.
Some have argued that Cactus Wiki’s open-editing policy leaves it vulnerable to mistakes, but Cactus Wiki proponents insist that such mistakes are an acceptable risk. Those mistakes, they say, are almost always corrected as soon as they appear. Proponents further argue that the risks are greatly outweighed by the benefits. When it comes to cactus information, no source is better than Cactus Wiki at gathering as many known facts about cacti as possible and keeping the articles up to date in the latest cactus developments.
