Week 4 Search for feeds

Had a quick look at these tools and not inspired by any of them in the limited time I had. Searched for a library topic as instructed on Technorati - erms (electronic resoruces management systems) and found mostly blogs using text shortcuts. Now intrigued what erms short for in text language. Checked out Feedster. Its search tips said that the results would hide multiple hits of the same thing but I didn't find that to be the case. Then looked at Topix which had a much more lively homepage but put off by the heavy US bias of the news feeds. Think I'd rather rely on word of mouth and serendipity than actively searching for feeds.
