It looks like I’m getting caught up!
I’ve been using del.icio.us to manage my bookmarks for a long time now. I can’t imagine going back to browser-based bookmarks though. I hated being bound to a hierarchical structure (unless I wanted to nest the same link in different sets of folders) and it was a nightmare to try to manage my bookmarks on multiple computers.
But I haven’t really gotten into the social networking aspect of the site. I share most of my bookmarks, but I can’t say I’ve explored the sites other people have bookmarked. We created a del.icio.us account for our library, and one of the projects on my long to do list is to add the reference resources I’ve bookmarked on my own account to the library account so we can share them with our patrons more easily.
