Stewing with RSS feeds

My instinct was that RSS feeds would be bad news and what do they say about trusting one's instincts?!!
I have the account in Bloglines - that was an easy entree - and have managed to get the feed from the Powerhouse Museum's picture of the day - has turned up for twenty days. But I don't really know why - I click on 'subscribe' but am not asked to put in a destination so I can't conceive how the connection occurs unless the fact that I have an open Bloglines account is enough. But I suspect it is just within the computer, not going through Bloglines because when I look at my feeds on Bloglines it says I have one feed but I can't open it from there .. and I presume I should be able to?? But on the other hand I set up the initial feed on the CTC computer but it is showing up on the library computer which suggests it isn't just within the computer ... So if what I did was right it is very easy but it just seems to be too easy .... (But I am ITnitwit!!!!!)
I still have to find four more sites from which to set up feeds. But the general comments ... I can see RSS feeds being wonderful time savers for individuals and for specialist libraries who could nominate a single figure number of really useful websites/blogs. No more having to trawl those sites at regular intervals checking for the new material. But for the generalist library RSS feeds would be most useful for staff tapping into relevant professional sites rather than as a service for clients as it would be very hard to know which sites to connect to. They would also be a useful topic for a small group instruction module, providing a real service and again positioning the library as relevant and 'techno-savvy'. (I'm not sure how much the CTC manager knows about RSS feeds ....)
As someone else commented, it was hard to find suitable sites from which to set up feeds. I tried a few way-out things like African cooking and Iceland looking at websites rather than blogs but I assume if you click on the RSS logo (on the menu bar, not within the window) and it says no feeds detected, you can't set up feeds. I found an RSS logo on the diabetes section of healthinsite.gov.au/topics but coudn't get the feed to work. Also I couldn't get a feed set up from Annabel Crabbe's blog on the Herald site. When I clicked on the RSS icon the screen went back to general news. So all in all not quite an unmitigated disaster but not a real success either ....
