"TagCloud is an automated Folksonomy tool. Essentially, TagCloud searches any number of RSS feeds 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."

I created a quickie cloud of a few of my favourite ASP.NET RSS feeds. I think the blah blah ones may have come from me, but I'm not sure.
