What's one metric you stopped caring about?

Mine is email opens.

I used to refresh campaigns like an idiot every time I saw:

Opened 6 times.

Opened again.

Opened from a different device.

Thought it meant someone was interested.

Most of the time it was just Apple Mail doing Apple Mail things.

Nothing happened.

Now I barely even look at opens. If replies are good, I don't care. If replies suck, I don't care how pretty the open rate looks.

Made me realize there are probably a bunch of metrics we all pretend to care about because every tool puts them on the dashboard.

What's yours?
