Not trying to be mean, but there's not much content here. It's a definition of the term "stringly typed" (from another blog) followed by the idea of using appropriate types.
I guess the author is "one of today's 10,000", as they say. Wiktionary attests the term from 2019 but I'm sure I've been hearing it much longer than that.
I was working with the Torque Game Engine in like 2008 which had a scripting language where almost all data was strings. Vectors? String of three numbers with spaces in between. Looking back I think it was kind of TCL inspired. But I definitely heard it called "stringly typed".
