To take things one step further, we could do away w/ multiple tags entirely if:

sub-contexts could belong to more than one context.

Imagine having a way to edit the @Home context and tell it what other contexts it contains.

@Home could contain things like
-- @phone
-- @online
-- @mac
-- @pc

@Work could contain
-- @phone
-- @online
-- @pc

Extending it further, we could do @Mall contains
-- @hardware store
-- @grocery store
-- @electronics store

Using this sort of organization, we could simply remember that buying milk is "@grocery store" and not have to worry about "I want to get groceries before I go home today, so add that to @work/grocery store".
