Instead of getting rid of qualified immunity, let's extend it to everyone accused by the government of violating the law. Why should we hold ordinary citizens to a higher standard of compliance with the law than we hold those sworn and paid to uphold it?

Huge thank you to @united ground crew in SF today. Had what could have been a travel disaster (not United's fault at all) saved by extraordinary measures by amazing people. Thank you so much.

This!
Replying to @AriCohn
People who talk a big game about being principled where othere are not should expect to be, and indeed welcome being, held accountable on those claims.

Conversation with my wife after I explained plan for getting garbage cans to garage: Her: Why must you always try to be so needlessly efficient? Me: A big part of my job is figuring out the fastest and most efficient way to get things done. Her: [In "that" voice] Oh, I know.

This is awesome news. This change reduces the ledger's vulnerability to halting without any sacrifice in decentralization.
The NegativeUNL amendment is now active on the XRPL. This important amendment provides resilience for the network when multiple validators are offline! 🎉

Some things of value are (ideally) completely fungible like money, cryptocurrencies, and gold. Some are completely non-fungible like collectibles and houses. But there are also a lot of things that live in a semi-fungible middle like concert tickets and airplane tickets. 1/7

Blockchains started out with completely fungible assets and are now moving to cover non-fungible assets. But there's a huge market for assets in the squishy middle that is very poorly-served today. That is the market for digital rights. 2/7

Digital rights are rights to access particular content through some service that provides the content when needed. They include video games on services like Steam, books on systems like Kindle, and movies you've purchased on services like Netflix, Hulu, and Amazon Prime. 3/7

These are very badly handled today. Your rights are spread out over many services. And each right is tied to a particular service such that abandoning that service means abandoning that right. This isn't good for anyone. 4/7

It sucks for customers because if I decide to stop paying for Hulu, I lose all the movies I bought. Hulu might stop working with the devices I want to use it with or raise their rates, and they hold some of my rights captive. 5/7

It sucks for rights sellers too. If you have a hit movie, you have a window to get $21 for it when it's hot. But if buyers worry they'll switch streaming services before they want to see it again in a few years, they'll rent it instead. You lose the premium sales. 6/7

Markets that bring buyers and sellers together that aren't built for the convenience of either the buyers or the sellers are ripe for disruption. This may be a big part of the future of public blockchains as the digital rights market is massive and massively broken. 7/7

Which is worse, if he knows this is complete nonsense or if he doesn't?
Yes, political speech is the most protected speech of all, but political speech that promotes or leads to violence is not protected under any circumstance. #Gosar
