Forgive me if I’m the last to realize but this but I only just started using Bloglines (other reader went boom). It’s a free rss aggregator that also includes a blog. You can set your blog to be public or private and send items to it directly from your feeds list.

What occured to me is that a library could set up an account and share the login among the employees (or just the librarians, reference dept, etc.) and share the work of keeping up with various feeds. Each person could review a certain percent of items a day and send the ones they thought were important to the blog where the others could see them and they would be kept for future reference.

It might be a cheap and easy alternative to setting up an intranet or a free public blog.
