             | 
             | I can stroll up to the White House and declare that I own
             | it, but I'll struggle to convince a sufficient number of
             | other people that this is true. If I can't assert my
             | ownership, then I don't really own it, do I? It doesn't
             | matter whether it is just, or fair (again - purely human
             | constructs), ownership only matters if it can be enforced.
             | 
             | Being a human construct, it is also by definition
             | temporary. It is only valid as long as humans are around to
             | enforce it, and humans are fleeting. Humanity might endure,

             |

             | willing to kill- or be-killed for asserting their claims.

         | I think the sticking out part is supposed to irritate somewhat,
         | but it still needs to make some sense, like a hot take. I
         | noticed some online personalities use the same strategy with
         | pronunciation, consciously and consistently mispronouncing
         | specific words, play up their accent. Media analysts also
         | recognize verbal tics as a trope, for similar effect.

         | Back to fonts, another site that I remember using a similar

         | establishing their presence, they used the square character
         | forms from the Programme font, which you can see on my link.
         | They still use Programme, but use the normal forms for some
         | time now though, presumably, because it was indeed irritating,
         | and it hurt legibility.

             | don't even enter the picture, very similarly to creative
             | work - for a musician, talent itself does nothing. Same for
             | well-written code for software engineers - nobody cares,

             | 
             | Usually the recipe for success includes good quality /
             | talent, sure. But it also usually includes something that
             | is markedly different from others. People, searching for
             | this distinct something, can seem tryhard, or just throwing
             | sh!t at the wall, to see what sticks - and maybe they are -
             | but they are also doing something that's an organic part of
             | the road to success.
             | 
             | For a font-related example, that might be easier on the
             | eyes, could be Fira Code. One of the immediate
             | distinguishers is the ligatures. Check it out if you
             | haven't already, it's quite neat, and it was the talk of
             | the town for quite some time.
