  • I think it’s a different thing. For me, my expectation is that Threads/Meta connecting to Fediverse is more like when AOL connected to IRC (specifically EFnet) in the 90s. I wasn’t really into Usenet, but Eternal September was pretty much the same wave. AOL pushed hard in advertising and recruiting users, and IRC and Usenet were originally populated with people who got into it more organically.

    I don’t remember Jabber or XMPP having any kind of discovery system. I only ever talked to people who knew already. So when Google connected Talk, it was just added convenience. I wasn’t bombarded with rude idiots like the AOL invasion of IRC. When Google ended XMPP support, I was disappointed, but I continued using XMPP with my friends.

    I think Meta is spending a ton on promoting Threads, and it’s going to bring in a lot of people with different values. It’s going to be unpleasant for me, but I think that’s just the self-similar fractal that is the Internet.



  • This. I think every culture has beauty standards, and some of them inspire a lot of people to do pretty drastic procedures. It’s pretty mainstream in America to covet straight, gleaming white teeth.

    I’m guessing there’s some long history of orthodontics in USA that intersects with phrenology, marketing to people’s low self-esteem, and piggy-backing on government and orgs’ campaigns for dental health (extrapolating from medical necessity to aesthetics.)

    Also I think there’s a weird thing where parents are paying for braces for their kids. Notionally parents want their kids to be confident, but I also sense an undercurrent of social signalling of wealth and status, along the lines of putting solar panels on the north roof of the house if that’s where the neighbors will see them.





  • I agree with all of that. My intuition is that prior to curing, the polymers are less stable and may change in unpredictable ways depending on subtleties in the storage environment and handling. After curing, the polymers are much more stable and durable.

    Metals definitely are more forgiving, and we have better tools for testing, especially non-destructive testing. Whether the CF flaws are due to fatigue or workmanship, it’s easy to miss them in inspection.

    I’m also curious what the sub designers saw as the advantage of CF for this application. Is light weight really all that advantageous for a submersible? Generally no one chooses CF if they are prioritizing cost.
