There is really no reason to use Google Analytics anymore. There are many great alternatives now, mine is PanelBear.com. Other people love Fathom and Plausible. It’s great to see some unbundling happen.
The alternative offerings at the time were fairly awful compared to what google released.
A rough “how many came” is useful. At least to diagnose if the site had problems. Just talk to people and make your thing good!
