       | much love though. I'll see if I can get this post added to the
       | second chance pool[1] and get it added to the front page!

         | Added! Thanks for requesting this.
         | 
         | All: if you seen a particularly good submission that has fallen
         | through the cracks, please email hn@ycombinator.com so we can
         | take a look and maybe put it in the second-chance pool
         | (https://news.ycombinator.com/pool, explained at
         | https://news.ycombinator.com/item?id=26998308), so it will get
         | a random re-upment on HN's front page.
         | 
         | (Yes, it's permissible to request this for your own stuff, but
         | we like it better when it's something you just ran across
         | randomly and realized was interesting--as mmulet did in this
         | case!)

       | "bad" smelling stuff: smoke or garbage. When people had covid-

       | stuff.

         | Still have it, intermittently. A sort of nameless-but-familiar
         | "chemical" smell that comes and goes, along with any sense of
         | taste. That is, I have bad days with no taste, just a chemical
         | smell. Other days I have a pretty good sense of smell,
         | generally with a good sense of taste.

         | Intriguingly some of the really unpleasant smells never get
         | through to me - I could probably work at a sewage works now.
         | Worryingly I have next to no ability to smell burning, though I
         | do now get the smell of natural gas (or the additive used to
         | make it smell).

         | 
         | The porn industry has historically been very quick to adopt new
         | technologies, it's easy to see how this could benefit that
         | industry, so it's a logical enough conclusion to draw. They'll
         | very likely be the first commercial application of this, once
         | viable.

         | Well, if it's waves, perhaps principles of consonance and
         | dissonance might apply. Robert Hooke thought so...
