RSS and newsfeeds

The thing that impresses me most about searching these sites is the wealth of information out there, and the need for some discretion when viewing information and considering reliable sources. I thought Topix.net was pretty good for finding news items that are more likely to be from reasonably reliable sources such as newspapers and other media outlets. Searching for feeds could be useful for business or leisure purposes. For example, using Technorati I searched using the keywords 'viola' and 'violists' (in my other life when not being Shopping Woman I am a very keen amateur violist) and found a number of interesting links, including one mentioning the Arizona Viola Society on a blog called 'Major League Jerk : the daily ramblings of men with no professional experience and even less social tact'! The Arizona Viola Society apparently played the national anthem before a football game. I guess it shows as well that you need to be pretty specific with your searching and spend time evaluating results to really make the best use of these tools. Although Bloglines was the most comprehensive in terms of finding all sorts of feeds and citations I found the others mentioned here easier to use with more meaningful results.
