IDS Cheetah already has its own community space, see the preview here: http://www.ibm.com/developerworks/db2/ids.
Er, what is a space?
From the developerWorks Spaces Wiki FAQ:
A space is a Web micro-site with one or more owners who can manage the content, presentation, and distribution with an easy-to-use interface. Spaces usually combine multiple ways to create or collaborate on content such as blogs, forums, wikis, file-sharing, video sharing, and so on. They may also provide ways to distribute the content via Web feeds such as Atom, or RSS.
Much more than a home page, a space allows the owners to communicate and connect with others. Each space is a potential community of its own: a following around an expert, a community of interest around a topic, a software project community, a user group community, and so on, based upon the wishes of its members.
The way it works, as far as I can tell, is that as the creator or maintainer of one of these spaces you choose from a selection of portlets to add to your page, examples include: blogs, feature stories, lists, forums, lists, podcasts, RSS aggregators, custom feeds and more, thus creating your own portal/aggregation site. These portlets can be dragged around the page and various layouts and themes chosen to suit your aesthetic proclivities. You can add up to 10 co-editors.
It will be interesting to see how this idea grows. If you feel like starting your own space, apply here.[Read More]
