Recent posts are dynamic and correctly rendered
fixed navigation posts <-> post
added slug as tag.id
posts and post with details - still no comments
list posts for a given category
side menu done (search and archive to do though)
fixed navigation with categories

GOTCHA: model is only used when entering the route with the url, but not
when a linkto is clicked. In this case, I have to detect the current
model is provided by linkto and not by model to load the posts for the
category.
