The enterprise collboaration and content management space is a crowded one. Depending on what you want to empower your workers to do, you can look at anything from basic wikis to Microsoft SharePoint to Atlassian's Confluence - to name just a few of the choices. Cyn.in, which until recently had focused on a SAAS approach to providing this functionality, has recently launched its version 2.0 - and now it's available as open source as well.

One of the nice things about open source software is that it can experiment easily. Projects that don't have an obvious commercial route to success can still thrive and prove their usefulness, free of the demand to make money. One interesting project I've run across recently is WikidBase, which as the name implies crosses a wiki with a database.

You may not have heard of Wikia Search before. A relatively new project from the Wikipedia folks, they've entered the search-engine fray with an attitude that is just about as open as it is possible to be. Not only is their underlying software open source (under BSD licenses), but the very search results themselves are as open to editing as Wikipedia pages.
