I have Safari, Anybox, and Alfred, and the three works together in a nice way to save anything interesting quickly. And once in a while, I comb through the inbox and sort them out. If I ever need to explore a subject, I then have a collection of links ready. I feel uncomfortable whenever I have 10+ tabs open. It felt that I’m not focusing enough on my research (taking the proper time to read and reflect in order to find a solution).
The only things I hoard are books. They are more like my antilibrary (things I’d like to have read already) than collecting everything I encounter.
