Actually, we are only creating one object in the database. You can think 
of our database as sort of a big "soup" of objects that can be grouped 
and viewed in many different ways. While we don't have explicit obvious 
"tagging" support in the UI, all of the infrastructure is there. In fact 
you can really think of a "tag" as a collection, or vice versa.

the "trash" is unique in that anything in the trash (or tagged as a 
trashed item) is invisible in the UI.. so by deleting something you're 
really putting it in the trash. if you take it out of the trash it can 
(and should, hopefully) go back to all the places it was previously.
