Widgetbox widgets "componentize" applications and Web sites, making them portable and transferable across any Web site. To date, the focus has been on consumers, but the integration with a clear enterprise business product like Confluence is a good step behind the firewall. The company also recently introduced Blidgets, which take any feed and turn it into a widget.
For those of you who aren't familiar with the Confluence wiki and Atlassian's bug-tracking tool, Jira, they provide free versions to open-source projects and accordingly have a huge market presence in the open-source community. They also happen to have a very good business selling their tools as one of Australia's fastest-growing software companies.
The Atlassian tools are utilitarian applications that get the job done right. However, once you get involved in seriously trying to customize your wiki or bring in outside applications and data, you quickly hit a wall.
Besides my obvious suggestion of incorporating video games into your corporate wiki, Widgetbox can help you bring in and manage all kinds of news feeds, as well as data from other sites, with in a much simpler manner then previously available.
