I think short urls are still memorable and good. My phone doesn't surrogate all of my recall.

The longer the text you need to store, the bigger a QR code needs to be in order to scan reliably. Also, you might be more confident in being able to keep a short URL stable (it's already a step of indirection, so if you want to reorg your site you can just update where the short URL points to). But people don't really take care to maintain short URLs anyway, apparently.

I think reading helps quite a bit, especially writing about what you’ve read, even to yourself, just so you can go through the process of having to explain something that you’re only recently familiar with. There’s something about that process that seems to be helpful, at least to me.

Same. The way I consume information influences how I think. Short form content makes my thinking fragmented without a clear structure. I feel that fragmented thinking won't lead to convincing writing. And I'm trying to regain some of that lost control.
