Small-Scale Question Sunday for June 29, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Homeowners of The Motte -- what would you differently if you could do it all over again?

I plan on building a house in the next 12 months on a lot about an hour away from the Gulf of Mexico America. It's going to be a two-story 5BR house with porches on the front and the back, built in a traditional Southern style.

I'm a bit overwhelmed as I don't even know what I don't know about building, and I want to avoid making costly mistakes that I'll have to pay to renovate later (or worse, be unable to fix at all). Happy to hear both from people who built and people who bought.

I own a 100-year old house myself, but my friend who has built new strongly recommends installing central vacuum lines during construction.

I lived in a house that had these once when I was a kid. It was pretty cool, you just plugged a tube into the wall and could instantly vacuum. But as an adult I'm wondering how on earth you'd clean and maintain such a system. I imagine I'd have to pay the manufacturer to clean, and after 10 years they may no longer be in business. I hate the idea of "dead tech" being embedded in my house, outdated gadgets look ugly and silly. I'll have to research how it works.

But as an adult I'm wondering how on earth you'd clean and maintain such a system.

It is self-cleaning.

While it is inevitable that some dirt settles at seldom-used outlets (especially those at lower points in the plumbing run), that problem tends to solve itself as soon as you connect a hose to that port by consequence of what the system does. And since when you're vacuuming an entire floor you'll use (almost) every port at least once, the remediation for ports seldom-used is "connect the vacuum line and run the system briefly".

Additionally, the hose opening tends to be a smaller diameter than the vacuum lines. So if you suck up something absurd, like a plastic bag, if it'll fit through the hose, it'll fit through the lines just fine. It would be wise to leave a couple of access ports, though.

The only real fail points are:

  • the central unit itself (generally quite reliable, it's just a nicer Shop-Vac- solution: replace unit if it burns out somehow, hookup is standard)
  • the hose between the vacuum head and wall (generally, electrical outlets are installed right next to the vacuum ports so you can run the vacuum's power head; the cord for that is embedded in the hose and will degrade with use- solution: replace hose, they're all standard)
  • the access ports (just a sufficiently-airtight door with 2 low-voltage electrical contacts, both properties can degrade over time; when you connect the hose, the circuit is bridged by the metal and the vacuum starts up- solution: replace door)

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
