I’m glad you found something useful here. I have it in mind to write a more general post about sidebar blogrolls and link blogs, the how and why of them, but in the meantime I thought it might be good to at least provide an update on my own progress. I really like the kind of blogroll Dale has at mole, too — Blogger is much better than, for example, WordPress.com for that kind of thing.
It was fun to find an excuse to play around with custom post types, WordPress’s most CMS-y core feature to date. As with my deployment of custom taxonomies at Moving Poems, it’s a feature that I may never use more than once, but I think it’s just the right tool for the job.
