Well, here's how my contexts have finally broken down (so far):
@ Home
> @ Spare Time
@ Lab
> @ Lab Meeting
> @ Bench
> @ Desk
> @ Ordering
@ Call
@ Computer
> @ Online
> @ Email
@ Errands
> @ Target
> @ HEB
@ Spring, TX
@ Harlingen, TX
@ Waiting

I have a specific subcontext for my spare time at home because it was easy for me to spend all my spare time playing WoW or finding the ends of the internet instead of working on various projects, but I also needed to keep them separate from the things at home that needed to get done.

My Lab contexts took quite a bit of refining - I was creating lots of subcontexts here that seemed like good ideas at the time, but never used. Ordering may seem like a strange one, but there's a set time that I do our lab's ordering, and I wanted to keep them out of my desk.

I also have contexts for places I visit frequently (Spring and Harlingen) where my parents and inlaws live. I may one day add subcontexts for Austin, Dallas, and College Station, but right now I just don't visit them enough to have specific things to do there.

I tried using Agenda contexts for important people, but I discovered the 'who' to wasn't as important as the 'how' or 'where'. It ended up being easier to search for a name to see all the tasks concerning them.
