I use Pocket to postpone reading articles during the work week. I then go through the list over morning coffee on weekends on my e-reader. Once I removed that impulse to read articles immediately as I stumble upon them, I found out that I simply delete like 50-60% of collected links without consuming them. I read books either after work / later on weekends / before bed.
I also have a two or three layer setup. I star the material in rss reader, then if it looks ok after some time, I add to Pocket. I skim the article in Pocket and if it looks worthy enough, I favorite it and an IFTTT rule adds it to Instapaper. I read once more in Instapaper.
In my opinion, if you don't think you'll revisit an article, it's not worth reading even once.
