RSS is great - you can keep up to date with news without having to search for a needle in a haystack(searching the net can sometimes feel like this!). I will just have to remember to check bloglines plus remember the correct passwords!
Having said it is great - what is not so great is having to log into bloglines to get the information. It would be good if you just receive an email possibly once a week to say when new info is available.
Libraries could take advantage of this by having links to the catalogue when new titles come into a persons saved search. You could let people know what great new services we offer or events that would be coming up.
Here is my link for my bloglines account - don't know if it will work but have a go.

News Feeds seem to be a bit more problematic. I haven't found them as easy to use as RSS. It may just take my brain time to get used to how they work.
