Actually, SNOBOL is a 1960s programming language[1], so it wouldn't have been a trendy new language in an 80s version of HN.
In the 1960s, most programming was done on punched cards, and keypunch machines (and many computers) didn't have lower case letters on them. Hence, languages from that era, like FORTRAN, COBOL, PL/I, LISP and assembly language, were written in all-caps.
