I've arrived at item #9 in the 23 Things training, which is titled "Finding Feeds." I'll address the questions that are provided.
Which method of finding feeds did you find easiest to use?
Frankly, none of the three resources provided were ones I'm likely to revisit.
Which Search tool was the easiest for you?
I like Technorati's interface the best, although Syndic8's information about the last day of update could prove useful to find sites that are regularly updated.
Which was more confusing?
Topix wasn't confusing, but it's not my cup of tea. If you want to find feeds on the latest celebrity news, try it.
What kind of useful feeds did you find in your travels?
I discovered Library Garden. The top posting was about the Webware 100 awards, which will provide hours of browsing pleasure!
What other tools or ways did you find to locate newsfeeds?
Almost every blog or web page that I'd like to track offers an RSS button. I'd rather search directly for a site than cruising around Technorati or Syndic8.
