RSS feeds, first the domain of news sites and blogs, are popping up everywhere in the Age of the World as Publisher. Digital warfare is rapidly shifting from search engines to feed suppliers, with an explosion of features fortelling the coming collapse and consolidation. Enjoy it while it lasts. Here’s a roundup of some of the latest:

NewsGator Online is a free service to track your favorite news, topics, or sports team across many different sites, all in one simple page that you create. They also have a version that works with MS Outlook, and premium services, both for pay.

RSS information site Syndic8 is now providing better RSS feed search results by listing feeds in order of relevance, according to search guru Tara Calishain at ResearchBuzz. I visited Syndic8, but found no evidence of the claim. In fact, I couldn’t even find the feed for my own blog until I backtracked and started at the home page. Then it came up on top, but with an old address. If you’re interested in only a few categories of search information, you’ll like the fact that ResearchBuzz now has category-specific RSS feeds from the category page of your choice.

Meanwhile Feedster is now offering an RSS feed finder, still very much in beta testing. It claims a database of over 900,000 RSS feeds. The University of Saskatchewan Library has a directory of ejournals with RSS feeds, for the academic minded individual. Visit http://library.usask.ca/ejournals/. For another source of keyword-specific RSS News Feeds, try All Headline News, a news search engine with about 7800 sources and keyword-specific RSS feeds.

You can get all sorts of feeds of Writer’s Edge, Georganna’s blog.
