I understand what you're saying, I just don't see what bearing it has on what my original point. The point I made was that, for people working in one location, there's little value in a location-based context like @anywhere.
I also pointed out that if you have a job that has you in different places - as yours appears to - then a location-based context like @anywhere could certainly make sense.
I certainly never said agendas or tool based contexts don't work for people working from home. Most of my contexts are tool based.
All right, if I misunderstood you, my apologies. We're having what amounts to a conversation. Communication isn't an exact science. Sometimes people misunderstand each other.
I think the place where I misunderstood you is when you wrote, "For people who do a lot of work in the same location (eg people working from home) I'm increasingly of the view that contexts represent little more than moods - ie what do you feel like doing now?" When you said contexts -- plural -- and said they "represent little more than moods," I thought you were questioning the value of all person/place/tool contexts for remote workers.
I know you attempted to clarify when you wrote, "Rather that the rationale for how we apply contexts is different these days to how it was explained in the original material." In my mind, connecting that with the prior statement I quoted, it sounded to me as though you were questioning the rationale for any "traditional" contexts.
I'm not quoting you to prove "you said it wrong!" I'm not trying to back you into a rhetorical corner, argue with you, or prove a point. I'm just asking you to understand that I'm not being deliberately obtuse or trying to argue with you. I'm actually trying to understand you. It's tough to read tone from words on a computer screen. I'm getting the feeling you might -- MIGHT -- be showing some irritation here. If that's the case, I'm just hoping you'll take my word for it that I'm actually trying to arrive at an understanding here.
So... to your point about @anywhere. Well, at the moment I'm unemployed. So... most everything I need to do aside from @errands I can presumably do from my house, right? But... losing my job didn't turn me agoraphobic fortunately.

I do leave on occasion. To me, @anywhere could still represent things that I can literally do... well, anywhere.
That being said, I've always gone back-and-forth on @anywhere. I just don't know how many things there are in my life that I would truly want to do no matter where I am that wouldn't be caught in another contexts (@calls, for example).
So, again, I'm not trying to argue with you. Like I said, this isn't an either-or. It's just that I have a different point of view. I could see a rationale for the "house-bound" worker to use @anywhere. I could see a rationale not to. You pays your money and you takes your choice.
