"There’s no limit, Alt text should be as long or short as it needs to be, just succinct and correct. Just not super long." Happy that this gets debunked by Chris Yoong because I've seen it again in yet another "white paper" (maybe written by AI, who knows?)

100, 150, or 200? Debunking the Alt text character limit
The arbitrary limit can be built into input fields and automated tooling

How Trademark Ruined Colorado-Style Pizza
You've heard of New York style, Chicago deep dish, Detroit square pans. But Colorado-style pizza? Probably not. And there's a perfectly ridiculous reason why this regional style never spread beyond a handful of restaurants in the Rocky Mountains: one guy trademarked it and scared everyone else away from making it. This story comes via a fascinating Sporkful podcast episode where reporter Paul Karolyi spent years investigating why Colorado-style pizza remains trapped in obscurity while other regional styles became national phenomena.

Will agentic browsing be the next big thing?
I remember back when site-owners said "my site's not usable on mobile phones because nobody buys anything with a mobile phone on my site" - don't fall into this trap with agentic browsing.

Agents are coming for your traffic and revenue. This shouldn’t be considered a bad thing! Except… if you don’t know whether agents can correctly navigate around your site or not.

If you need images and have none just use one of the free stock image sites. It's not harder and doesn't make you look like a dumbass.
