After you have an RSS feed reader and know how to subscribe to RSS feeds, how do you find feeds?
You can find RSS feeds using Search engines.

Refer to the Venn diagram above:

Which blogs are included in Blog Search?
The goal of Blog Search is to include every blog that publishes a site feed.
To refer to the chart above, the Google blog search does not include all blogs or all feeds. It is a search for blogs with feeds, which is the green part of the chart.
In the Yahoo advanced search, there is an option to restrict the search to RSS/XML feeds. The File format option has a drop down menu that includes
File Format Only find results that are: RSS/XML(.xml)
The results will be noted as follows:
Your search was restricted to "RSS/XML (.xml)".
There is enough overlap of blog and RSS feeds to consider using Blog searches to find RSS feeds.
