Ask HN: Anyone Here Using Stenography

Hi, I just discovered what steno is and it seems really cool. Right now I am just blown away by how fast some stenographers can type. I am thinking of buying a Uni v3 but wondering if the amount of effort it’ll take to learn steno will be worth it. Does anyone here use steno for programming or just writing in general? If you do, do you have any tips on how to learn stenography faster? Thanks in advance.
