That does sound like a pretty 'relational' approach to me. It's not that you can't do this,
but you might want to consider blog posts to be a self contained document, since it makes
some things more relaxing (updating an author's name would be less relaxing, but how often
does that happen?). Doing away with 'joins' can really be a relief!
