There are companies that host wikis for free or for a price. This means that you do not have to deal with complex programs like Ruby, PHP, MySQL, or Apache. The wiki host will do this for you.
Beware! Some hosts delete wikis without notice. Make sure you are saving your own backup copy of the data in your wiki. Some hosts make it easy to download everything you would need to run your wiki somewhere else, by using an open source wiki engine and providing backup dumps with full edit histories. Other hosts lock you in more, e.g., with proprietary wiki markup languages, proprietary wiki engines, or limited backups.
