While we're on the "new ways to categorise" round-up, Zoundry Blog Writer has been enhanced with a "tag for del.icio.us" option in the compose window. See the Zoundry Blog and Central Park Bench. My question for Stewart. Do these tags have a rel="tag" attribute that will enable them to be picked up by a wider audience? If not, is it possible to configure Zoundry to add this feature? Looks like another great way to add categories!!
Here's the Zoundry Forums how-to, if you're a user & want to add this functionality.... and looky, there's the rel="tag"!!
