When I switched to using Bloglines, I somehow lost a lot of the sites I'd been linking to. I'm not sure how that happened, but it did. Every now and then, on one of my rare visits to another blog, I'll see a link to a blog I used to read often, but that I never read anymore because it didn't make it to my Bloglines list.
So I've added back a few that got neglected. Some are already categorized, and some are in "New to the Blogroll." Not that I have time to visit any of these ... it's just nice have them back in my blog-reading life, limited as it is!
