Ask HN: How do you find iteresting stuff on the internet?

There is so much interesting, cool, and entertaining stuff on the internet, but I feel like I'm falling short on finding it. Any suggestions on how to do that? No constraints on what the material is. I just want to know how you find cool stuff online!

Also, please refrain from posting advice on how I shouldn't do this because it's nothing but entertainment. I realize that and am doing this purely for entertainment where I probably might learn something.
