Most of the time reading for the reasons others have stated(scannable, copy examples, etc). That said, there are times where I read something a number of times and the concept still doesn't click. In those instances a short video of just that specific concept is great. Short, hyper-specific screencasts are useful where exhaustive videos are not as much (to me).
I know Atom is still in its infancy so this is not a bash on it at all. The vim mode is what gets me. I keep using Sublime mostly because the vintage mode is quite good in comparison.
I really want to use Atom for the reasons you stated :)
I purchased it a long time ago. I know of others who have as well. It's nice they have the never ending demo -- but I'm glad people pay for it. It's a great editor.
Not entirely apples-to-apples but there was water contamination in west virginia earlier this year and it was over 5 days before water drinkable again (that was due to a spill though and not algae).
This is why I get most of my news from the Internet. The other news stories are definitely important but being in the toledo area (thankfully in a town that doesn't get water from Lake erie) kind of gives this one a bit more immediate relevance.
I've been finding 8.1 really nice also. Design apps like Photoshop / Macaw etc work fine in Windows... for things like Rails / Node (stuff that seems to be a better experience on Linux systems...) I've been using Vagrant to setup a box specific to the project.
