Depends on what kind of data, if it’s mostly internal documents / dumps of whatever communication systems they use etc, it would not be too large (mostly because of retention policies on that software).

If it actually data straight from Reddit’s production databases, then 80GB does sound questionable. But then what kind of data are we talking about? Is it actually valuable?

Anyways, this is big (if true).

I use https://reeder.app/ with https://feedly.com account. Checks all the boxes between being able to access my RSS feed on any device (as Feedly has a website) and having a great user experience on my phone / laptop.

You can also star the repo on GitHub and enable release notifications, I assume the developer will create a release once the app becomes usable.

I mean, you can probably use whatever reminders app you have on the computing device variety you prefer :)
