Start your own video wiki at WikiVideo

Wikipedia is undoubtedly a very successful wiki project. Since then, many web companies join the wiki market to allow you to start your own wiki. Among the most popular ones are:

PbWiki - recently, PbWiki introduced the version 2.0. It has some nice features, but the data storage limit for free version is too limiting.

Google Site - it is part of Google Apps. Hence you need a Google Apps account in order to use it. To sign up for Google Apps account, you need to own a domain name, e.g. www.myCompany.com. Besides this restriction, it is a good choice too.

Wikia - everything is good except I cannot remove the footer that Wikia puts in.

Wetpaint - In my mind, this is the best wiki host. It has the best structure, thus it is easier for users to navigate within the wiki. It offers some very nice looking skins too. Again, same as Wikia, I can't remove the footer Wetpaint puts in.

But recently, there is a new startup joins the market called WikiVideo, which allows you to create a video/audio wiki. It comes with two languages, English version, and Italian version. Unlike other wiki sites, which you can only embed a video into a page, WikiVideo hosts your videos, i.e. you can uploads you videos directly to WikiVideo.

WikiVideo accepts all the popular video formats (AVI, MPG, WMV, MOV, MP4...). But the most interesting feature is, it doesn't convert your videos into FLV like YouTube. It simply displays the video on the web page as it is, which may be or may not be a good thing. The recommended file size is 20-100 MB, but I am not sure whether this is a strict rule or not.
