Same when it comes to staying on top of tech news -- almost everything is a flash in the pan. I used to bookmark cool new products, never revisit them, and then a year later realise half of the links are now dead.
One thing I realised though is I still need to mindlessly browse an endless feed every once in a while for some downtime. One way or another I'll want to fill that time with something, so it's a question of being mindful what goes in it. So my drugs of choice are Hacker News, and carefully curated YouTube subscriptions.
