I think the likelihood of one item appearing in multiple collections
differs depending on the domain. As just a pure Calendar app: rare
but not impossible (ie. An office event I am attending, so the item
lives on both the office calendar and my own calendar.)
As an integrated information manager, you can easily imagine users
creating all kinds of collections:
+ that are more than just (different calendars)
+ that are defined along "orthogonal" attributes: (ie. Project
collections and @People agenda lists)
In this world, the likelihood of a single item appearing in multiple
collections is very high.

Hi Mimi,
iCal gets around this by shipping out of the box with 2
calendars: Home
and Work + they have a big fat [+] button at the bottom of the

It is also possible that as Chandler becomes more of a "cross-
app" app,
the idea of creating "top-down" collections of items as a generic
way to
group items will neutralize the "set a category" mental model people
bring from other calendaring apps.
Yeah, this will hopefully happen eventually, but why not add a big
fat
plus of our own? I'd be supportive of that, anyway.
I suppose one worry is that people are used to the hierarchical
model of
items, it won't occur to them that add-to-collection isn't going to
move-my-item-out-of-this-collection. Making a big fat plus isn't
going
to solve that problem.
This is reminiscent of the drag-to-copy vs drag-to-move debates of
ages gone by. However, in this case, an item may belong to several
collections, so moving out of a collection (or all collections) is
not an expected/clear behaviour, is it?
Are we expecting that users will have items in multiple collections
as a matter of course? Or will it be less common than the one-
collection item? If one-collection items prevail, moving items to
other collections should behave as they do in iCal, where they
would be removed from the previous collection.
Maybe I need to read more design notes on the Wiki about this..
