The problem with this, I've found, is that you end up skipping a lot of things, and then find out later on that features were introduced years ago that you've wished, throughout the interim, existed. It's hard to keep up.
I wish there was regulation enforcing background colors for ads.
We should just have an <advertisement> tag in HTML, regulation could then require it.
I'm okay with missing things. As I got older, I cared less and less about being aware of everything out there, and I was glad I got the thing done I needed so I could spend time with my family.
