I have the impression tha for many people writing these kinds of posts, much of their world (hobby, work, etc) is actually online. Then I wonder, did these people cut down on software, too? How many webapps do they use? How much of a mess is their Dropbox?
I, for one, have had a very chaotic period of life or a very simple and structured one, best visible by how much a mess my computer was. Only regarding material goods seems a bit half-assed then, imho.
The difference is that physical goods have a much higher cost of maintenance than does digital ones.
I have way too many games in Steam and other digital storefronts, but I catalog the ones I care about and have come to the understanding that there are probably some games I will never play/finish. Those ones I just hide and never look at again. It's harder to do that with a boxed game on a shelf, which you need to keep room for, pack away when you move, and ensure it stays in reasonable condition.
My current software minimalism project: Stay with Ubuntu LTS. Do not upgrade every half year.
Upgrading Ubuntu usually means a few nice features, some things break, some new workarounds. For someone who is not using Unity there is probably no new feature in 12.10 anyways. While 12.04 has its quirks and bugs, at least my workarounds need no change for two years.
