This is how free and open access works. There is no way to have a free and open access project and then go “wait, no, not like that”.

Wikipedia turns 25 today! 🎂📚
To celebrate, we’re looking back at its baby pictures—some of the earliest captures of the site, preserved in the #WaybackMachine.

I deleted over 60% of articles from a real estate website. The CMO was nervous for 3 weeks. Then clicks began to climb.
The blog was full of "perfect" SEO content. EEAT compliant. Ranking. Yet, mostly ignored.
Few clicks. No shares. No deeper site engagement. Because it read like ChatGPT wrote it.

Mix during political and economic turbulence and serve.

I think this attitude will result in folks calling stuff AI that's actually just shitty human-written click-bait content and I'm absolutely fine with that.
if you're writing your post with AI, i'm not reading that shit to the end. not because i hate AI but because it's just not good enough. if i can spot it, it's skill issue both on your and AI part

Jan 1 - copyright date update day. Simple.
But it never is… as there are always out of date dependencies to sort out before a simple date change can be deployed successfully. This is the day of the year I miss using php.

What can 40 years of song lyrics tell us about society?
I analysed the lyrics of 1,600 pop songs going back to 1985.
Our music appears to be getting gloomier, less future-looking and more self-obsessed
