Hmm RSS

Ok I have watched the Youtube explanatory video on RSS, but I still don't get it, clearly having a dim moment! I guess it's because I don't understand why you want information constantly streaming in, I would rather seek it out when it suits me, for instance, I subscribed to Library Links and for a while read them religously when the arrive but now find myself dumping them in a folder in G'wise for reading later, which means they don't get read!
But I have set up with Google Reader with the recommended RSS feeds including the Powerhouse Museum one so I guess I can tick myself done with RSS for the moment
