I made a flow chart of which #Mastodon posts end up in which timelines!

So, you can see how each instance will have a different local timeline, and even a slightly different federated timeline - and you can see why the federated timeline moves so much faster than the local one, too.

Interesting proposal for a new fee-bumping mechanism: lists.linuxfoundation.org/pipe

Haven't read the mailing list responses, but bitcoin-optech has a nice quick summary: bitcoinops.org/en/newsletters/

It seems to me that this mechanism is a little worse for privacy (it will publicly link UTXOs that are otherwise potentially unlinked), but this seems to be a small consideration. Probably worth that risk in many use-cases, if it mitigates tx-pinning attacks.

These days everyone seems to be rather busy being anti-this and anti-that and anti-everything-in-between.

You know what? I'd rather people tell me what they actually stand *for*, not everything they are *against*.
