TagCloud Beta– create keyword clouds for any set of sites
TagCloud - Home: “What is TagCloud?
TagCloud is an automated Folksonomy tool. Essentially, TagCloud searches any number of RSS feed you specify, extracts keywords from the content and lists them according to prevalence within the RSS feeds. Clicking on the tag’s link will display a list of all the article abstracts associated with that keyword.”
TagCloud automatically creates a flickr style tag cloud based on keywords in any sets of feeds you want. I’ve created a tag cloud for Jobster so you can see what we’re talking about. I also made the cloud available in my sidebar by including a snippet of Javascript.
Cloud publishing should really be integrated as a feature into one of the other place where you maintain lists of feeds. (I can see this is a checkbox on my bloglines subscription list, for example.) The hardest part was having to re-enter all of the sites one by one.
