But there were so many problems! Lots of dreck I don't want to see in my newsfeed. Irrational decisions on suspicious behaviour made by bots that don't seem possible to contest or reverse, even posts being censored. I don't want to be supporting all that's wrong with what they're doing there. I passed the big reader group on to my author friend, don't advertise, and go on once a week for a very short time to reply to comments on my page.
A big thank you to all the hard work the moderators here give us to make Permies a safe and reasonable place to visit!

I really try and limit my time on them as I know they are trying to show me the maximum amount of ads possible. Old school forums like permies where it's actually just about connecting and sharing are where it's at!
Edited to add: anyone interested in that research, should check out the Behind The Bastards podcast episode 'Let's Look at the Facebook Papers'.

I keep my social media super tight. I'm only on one page, I block ads, and I don't "friend" people who aren't friends. It's a small group of people I actually know and have relationships with, and a convenient and efficient way to share events, announcements, updates, photos, ask questions, check in with people. Especially people I don't get to see regularly. I use it on a computer, not a mobile phone, so I'm unplugged 75% of my time.

It just seems like a slightly "better" form of modern concrete (and I'm not clear why it is better). It is relatively easy to design smaller projects (eg homes) without large amounts of conventional concrete anyway, and that will still be an environmentally better option than less-bad alternative form of concrete.
But where concrete gets used on massive scales, this is a non-starter. Architects won't be designing large projects around it's use because it is insufficiently consistent in it's behaviour to be guaranteed safe and predictable in it's behaviour.
At best I think this will be a niche concept for individual enthusiasts.

We live on volcanic soils, so super stoked to try this out sooner rather than later.
