To be fair, I thought about using something to just measure website traffic and in the end, decided against it.

I used to run Piwik as a self-hosted alternative to Google Analytics on other sites in the past, but that still gave me the option to view a ton of data that I didn't really 'need'.

I figured for this site I'll just measure growth on perceived activity and BW use over the course of time. This is the first site I've ran that I've not cared about SEO scores and search rankings, that I've not (over) analyzed data over to try to improve this random metric or that.
