Delving Bitcoin has some of the highest signal in this entire space. The authors on that thread alone bring back some serious OG energy that is sorely missing elsewhere.
What if the next big war in bitcoin is not *exactly* op_return or inscriptions or even just "spam", but, related: the "confiscation war" which will be about whether we can ever make outputs unspendable: sub 1000 sat outputs that bloated the utxo set so much at one extreme, and above 10btc outputs with exposed pubkeys from 10++ years ago, at the other end. There are a lot of influential voices advocating for things like this.
Credit to Robin Linus in that in this thread: https://delvingbitcoin.org/t/dust-expiry-clean-the-utxo-set-from-spam/1707 his second message imagines an ingenious way to *not* confiscate. Thread is most definitely worth a detailed read.

Indeed. At the same time there are a lot of new people providing very high quality input too, Robin Linus being one of them.
