I spent a lot of time trying to do stuff with ObjectiveC, but just hated the syntax. That's been the biggest thing keeping me from developing Mac OSX apps; I just prefer Ruby's simplicity. I'm going to seriously give Swift a try.
COBOL, Fortran, JCL (not Turing complete, AFAIK), SQL, Excel, DOS batch files all were (fairly) mainstream at some time.

More importantly, "inspired by" does not imply that Fortran 58 is Algol-like (that same picture would declare Fortran Lisp-like, too)
For me, http://en.wikipedia.org/wiki/Fortran#Simple_FORTRAN_II_progr... certainly is nothing like Algol.
Perl and C++ are still in the lead, but with stuff like the gratuitous introduction of alternate hash syntax, new-style lambdas, etc., Ruby is catching up.
