Use $blogStatus for GTD and task lists
$blogStatus is a set-type attribute. Fill it with meaningful strings. Then build an agent that collects (and sorts) notes according to $blogStatus. This will give you a sense of work that remains to be done.
Besides descriptors like draft, confused, private, fill holes, and clean up, you can create presorted status types by using a shared prefix.
For example, by using values such as as rating-1, rating-2, and so on, you could create an agent that collects all and only ratings by setting its $AgentQuery to the proper regular expression.
