I think the issue with blogs is things like Twitter solved: making it low effort to publish and promote content. I've recently thought that maybe a blog should really be a timeline (or similar) where you can tweet and posts simply exist as pages and show up on category/tag pages. You'd "tweet" your posts to a timeline and this would be what would normally appear on the home page and rss feed. You could re-promote an old post with a small blurb why it's relevant again. You could link to other sites with a blurb why. All the while you're not clogging up twitter and others since they can go to the website and see the information there (pull vs push).
