I love irc. I love irc.freenode.net. There are a number of wiki related chat rooms on there and a month or so ago, an acquaintence introduced me to yourwiki.net. It is a wiki hosting company that is run by a couple of friends. At the moment, they are pretty small and they aren’t focused on making money. Rather, they are focused on offering great support that being a small wiki host allows them.
yourwiki.net is a traditional wiki farm of sorts in that there is a shared user base across multiple wikis. This is similar to how PBWiki and Wikia work. This can be great for community building on your wiki because there is a larger pool of contributors from which you can edit.
They currently make some money with google ads. None of them are in the content area. In the near future, they will be launching premium accounts so you can have an ad free wiki.
If you’re looking for a first wiki and don’t want to pay for hosting, this is an option you might want to consider. The directs below are from their About page and tell you how to get a new wiki:
First, you’ll need to Login or Create an Account so we can keep track of who owns the wiki. After you have done that, you may request a wiki on Meta Wiki, our collaboration site about YourWiki. If you cannot create an account for whatever reason, just send us an e-mail and we’ll work with you; Just send us a preferred username.
If a big wiki is impractical for a small subject you want to write on, then you can create a Mini Wiki. Mini Wikis can be created by anyone. Although they aren’t full wikis, they’re still perfect to use for small public projects.
If anyone else knows wiki projects like yourwiki.net worth supporting, drop me an e-mail and I can happily plug.
