[SITE] Add logging?

[RoelN]

It would be nice to keep logs on which fonts are dropped, which types, etc. All with as little privacy-sensitive data as possible.

Immediately a good reason to opt-out:

I often use Wakamai Fondue for unreleased/upcoming typefaces, so an opt-out would be preferred — but some kind of summary could definitely be interesting to see

Collecting data on the fonts themselves seems undesirable.

But we can collect some data about usage. How to determine usage with non-interactive elements though?

For each thing that's detected - each language, each ot feature, each axis tag, each axis range - you could increment a counter.

Then you can use this aggregate data to know what is more commonly detected and therefore should have more/better treatment.

Eg, if small caps are very common but slashed zero is rare, a prominent section that shows off in detail what the former looks like is going to be more worthwhile developing than the latter.

No, as an offline-first app that specifically states up front that no fonts are uploaded, this is a good reason to make any usage reporting opt-in.

You could probably get a better idea of what features were rare vs. common by surveying recently released fonts. Also you might want to do the opposite: surface unusual features more prominently than run-of-the-mill features.

Neither of those points are to say collecting usage stats is bad ... I think it can be a great thing. I'd focus more on usage patterns on the page than on collecting data about the fonts people submit, and I would absolutely make it opt-in, but sure it would help inform development and UI decisions.
