RSS Feed Search Engines - helpful or unnecessary?

• Feedster - One of the largest collections of RSS feeds, Feedster lets you search for feeds in three categories: news, blogs & podcasts
  
• Topix.net - This search tool allows you to locate recent newsfeed items based upon keyword or phrase searching. The tool focuses specifically on news and media outlet RSS feeds for information, not weblogs.
  
• Syndic8.com - Syndic8 is an open directory of RSS feeds that contains thousands of RSS feeds that users have submitted.
  

• Google Blog Search This one is limited to blogs, but it can help you find blogs that might be of interest to you
  
• Technorati - Technorati is a popular blog finding tool that lets you search for blogs. Since RSS feeds are inherent to all blogging tools, Technorati Blog Search can help you find RSS feeds for topic specific blogs you may be interested in. We'll be working more in-depth with Technorati in Unit 14, but you don't have to wait until then to fiddle around with it.

Out of above RSS search engines I only found Topix.net and Google Blog Search to be of any use to me, and even then it was minimal. Feedster appears to be down and Syndic8 seemed poorly designed. I made some new subscriptions using Topix, mostly hot stories, redundant political blogs etc. I still prefer to make my subscriptions the old fashioned way by stumbling across blogs or sites I think I'd enjoy or like to keep up to date with.

I can definitely envision FVRL using an RSS feed at least off of the main page. To keep those itnerested up to the minute on what FVRL is featuring. From the ILSWiki I subscribed to one Library blog entitled Anarchist Librarian Web. The name obviously caught my eye and some of these posts turned out to be entertaining. I'm not sure if I'll continue to subscribe to it but that's the beaty of feeds, if you're tired of one just ignore it or delete it.
