I've actually been using Bloglines for about two years.
NEFLIN had a course in 2006 called "Social Software in Libraries," which introduced us to blogging, RSS and newsreaders, wikis, etc. That's when I first entered the "blogosphere."
I currently subscribe to about two dozen blogs: comics, political blogs, Quaker blogs, library blogs and others.
I just went through the process of marking each as either Public or Private, and I tried to create a blogroll on this blog, or at least to have a URL by which I could give access to my public Blogline's account.
Unfortunately, both methods show the titles of folders which have private subscriptions. I haven't found a way to block the folder names, so I'm not making any of this public for now.
I'll keep trying....
