Feedmarker is an RSS reader and a social bookmark manager tool in one.
Here is mention in a past post (scroll to the Feedmarker heading)
I already use Bloglines, but I find Feedmarker useful even if you don’t want to use it solely as an aggregator.
Start up an account
Subscribe to some feeds
Organise these feeds into folders, name these folders as you please.
Nothing different yet…
Feedmarker call the folders “tags”, and guess what, each folder has an RSS feed.
What does this mean?
I can subscribe to 10 or 20, etc..of my favourite library RSS feeds and put them in a folder called “Library”.
What I have done is made a compilation feed of all the feeds in the folder…(a la Blogdigger groups)
So take the folder RSS feed and subscribe to it in Bloglines or the reader of your choice.
When I check on that feed I have a stream of posts from all the feeds within it.
Now you can make your own topic folders or tags that hold your favourite feeds.
We are coming back to the idea that Technogeekery mentioned about creating OPML topic guides for library patrons or your clients…this is even easier to grasp for those new to RSS.
These RSS topic tags are different than OPML, as there is only one feed and the content from all the feeds within are read in one stream, whereas when an OPML is imported you actually import all the single native feeds themselves.
