A swiki is a "custom social search portal on a topic of your choice", says Eurekster.com. In effect, a swiki is a widget you put into a web page and chose the topics that you are interested in. Eurekster then creates a tag cloud based on the tags you supply. What's nice is that as others use your swiki, they can vote on certain search hits, to help the gadget generates more and more relevant content.
I've been playing around with this and have created a PowerShell-Stuff swiki, and have placed it onto this blog. I've also put an OCS-Stuff swiki over on my corporate blog. are these useful/interesting/helpful??
