Hierarchy of Communication

Once again, the almost ever happy James Whatley, has posted something that was in my "should post something about this idea" queue, before i manage to get my post out. So in response to that, i have mostly tied up my thoughts and here it is.

I had been thinking about this (but from a slightly different point of view), as i had been rather busy on multiple projects at my job recently. So busy in fact, that i got to mostly dictate the communication methods other people could use (which in fact turned out to be email only).

For me, i think of the various ways that other people send information towards me in a hierarchy of increasing order of interruption (something like):
Social network/microblogging
email
IM
SMS
Phone call
Face to Face meeting

Digging a little deeper into these,
- Microblogging or social networks
they have an "ambient intimacy" idea going for them == i check in when I have time
- Email
I can check this when i get a short break in the day i.e. 2-3 times per day.
- IM
pops-up on your screen, but can be ignored until you are ready to deal with it (or you can set your presence to be do not disturb or away if you need quite/thinking time)
- SMS
again it can be ignored, but is not usually. For me, this is probably my preferred method of communication (low interruption, little expectation of response, i can respond on my schedule if needed, etc.)
In fact, i have found that in Finland SMS is actually a very valid method of business communication.
- phone call
I need to be almost 100% focused for the duration of the call, with conference calls at least i find i can do small "tidying" type tasks (sort out inbox, desktop or temp directories etc.).
To a certain extent i also use the "divert to voice mail" to judge how important the call was (if they leave a voicemail, it was important!).
- Face to Face meeting
The most expensive in terms of interrupting me or stopping me doing something else productive, due to the fact that as well as the duration of the actual event, there is some period of time before and after the meeting where there is not much else i can do because i am focused on the meeting.

Now in terms of the volume of information that is transferred, for the interruption of time, i see it as something like;
Email is best (least intrusive, most information), face to face gives good value as you can draw pictures etc., SMS, phone call, im and microblogging brings up the rear (filtering out the noise from all of the status Updates can be a relatively major task)

Services like Spinvox would probably help me by moving phone calls further down my interruption hierarchy. In fact judging by my current phone behaviour, i might even just leave the phone in "silent" mode and never answer it again.

Getting back to why i was thinking about blogging this, was that i have seen that unlike James' pictures, I don't see the other half of the picture as normally a mirror. From what i have experienced, the order changes slightly, or some options are not even there.
Like most assumptions, this thinking that the other person likes to be contacted in the same way can cause dis-connects and friction.

EDIT: Follwing on from @whatleydude's comment/request, i created a diagram that sort of summs it up.
