This post on drunkenblog echoes my thoughts on a linkblog.
Some days I sorta wish I had a link blog, because I go through a ton of things every day I'd like to point others towards, but don't have a few paragraphs worth to say about them...
The obvious solution that probably comes to mind is sucking in something like del.icio.us bookmarks in some form, but that won't really happen because I have zero desire for the world to see all of my bookmarks, which means I'd have to maintain two sets, and I'm way too lazy for that....
