Ask HN: Is This Typical Procrastination?

Too much of my day looks like this:

I sit down in front of the computer to do some work. I think:

"Before I begin, let's check HN real quick if there is something interesting on the frontpage. Probably there is not, so I'll start my work in a minute."

Half an hour later, I realize I went down some interesting rabbit hole of information or joined a discussion.

Now I need a break from the computer. I stand up and do some other stuff.

20 minutes later, I come back to the computer to do some work. I think: "Before I begin, let's check HN real quick ..."

What is this problem called? Is it typical procrastination?
