It'd be helpful to be able to tag/filter posts (separately from Entry-Type); Entry-Type generally is used only for affecting layout/visibility, whereas tags are used for filtering with one or more attributes. (For example, in a comic, being able to tag entries based on characters or subject matters.)

An efficient strategy for implementing this would start with adding Tag and EntryTag columns to the database, where Tag provides the plaintext strings and EntryTag associates them with the entry. When an entry is scanned its EntryTag associations would be destroyed before the existing ones are added. Adding the appropriate joined expression to the view query is not something I want to think about right now.

Well, okay, the query would probably be something like:

select = select.join(Tag)
if type(tag) == str:
    where = where & (Tag.name == tag)
else:
    where = where & (Tag.name << tag)
