Twitter became unbearable, so I am exploring other social media options
If that tapers off now, too, that would be the likely explanation
I'm wondering whether the increase in BRC20 lately was mostly the ancient transactions in the mempool getting processed.
Depends on what you mean with "good". On the one hand, demand for block space is now lower, on the other hand, it's less likely that Bitcoin devolves into a casino platform like Ethereum
Runes have dropped off recently. 
Was there you a specific point that you wanted to raise per linking to this report?
Giving Nostr, Bluesky, and Stacker News another spin. Might even blog a bit more again.

Maybe they restarted their node and didn't backfill their mempool
Last night, the mempool shrunk to a depth of less than four blocks worth of unconfirmed transactions before it bounced back. It seems that we will soon see non-full blocks.
