I posted a couple of weeks ago about getting rid of my somewhat arbitrary RSS folder setup in favor of using no folders at all. As it turns out – for my needs – using no folders vs. organizing everything has made no difference all. I'm not missing anything I was getting to before, or annoyed by any difference in the order I read things in.
It makes me wonder what other systems I may have built up for myself that are really just me creating arbitrary labels instead of providing value. GTD contexts seem like low hanging fruit to look at next. For example, I'm starting to doubt the wisdom of dividing to-do items into categories like what app I'd be using, and tying them a bit more closely to physical opportunities and limitations.
