Khurt, I've only been doing it for a day, and it's almost overwhelmed me already, much less subscribers. I've started by saving all the data as either drafts or private posts, so it's only overwhelming me at the moment. I wrote a bit in the past about how do set things up so that email subscribers aren't overwhelmed with data like this and it's also possible to exclude certain tags/categories from your main RSS feed so that you don't scare everyone off with a massive firehose of data there either. https://boffosocko.com/2016/12/18/rss-feeds-a-follow-up-on-my-indieweb-commitment-2017/.

I've also been thinking about how all these posts potentially dovetail with my other listens which are almost solely podcasts and include mp3 enclosures so that others can subscribe to my faux-cast.

I've had a separate site for a long time collecting scrobbles from Last.FM. I suspect I'll start pushing all this data over there instead...
