Your comment inspired me to try all 3 tools in combination, and at first glance it seems like a very nice solution; certainly more effective than my current manual method. A quick question for you though, if you don't mind: do you use taskwarrior just as a backend for taskwiki or do you use it in its own right aswell?

I like the idea of just being able to add todo items quickly from a shell without opening the task list but I imagine those items would not be reflected in my taskwiki list without some kind of taskwarrior hook.
