Just a quick note: There is a feature planned called "virtual collections" for querying the embedded collection as if it were a standalone collection.

That way you could easily do db.posts.$comments.find({"name": username})

to retrieve all posts by a user, or

db.posts.$comments.find().sort({date:-1}).limit(10)

to retrieve the latest 10 comments on the blog.
