This does sound like it was written by an off the shelf LLM. You can't just rely on em dashes anymore, most LLMs don't spam those anymore.

When you tell a modern LLM to write a post like this, it'll use a very LinkedIn-esque tone. It'll spam short, active sentences, often preceded by a colon:

Document your setup. Write guides. Make it easier for the next person. Run services for friends and family, not just yourself. Contribute to projects that build this infrastructure. Support municipal and community network alternatives.

"Not this, but that" and the "rule of 3" are getting less useful as tells, but they are absolutely littered everywhere in this post.

When you run Nextcloud, you're not just protecting your files from Google - you're creating a node in a network they can't access.

I quote this formatting as a joke for obvious LLM writing. I've never seen human writing with more than 3 of these in a single post.

My guess is that this was written by Claude since it stays rather personally neutral if you don't guide it that way.

I made Claude generate a post like this and it's a very similar tone.
