This is an ideological question disguised as a technical question disguised as a linguistic question. As a linguistic question, it depends how you define "programming language". Some people consider anything that tells a computer what to do to be a programming language. Others consider it useful to separate programming languages from markup languages, query languages, assembly languages, scripting languages, etc. As a technical question, a lot of people jump onto "is it Turing-complete?" Personally, I think Turing-completeness is overrated and kind of a tangent. Finally, there's the ideological question. Especially on Twitter, similar questions are intended to break down the hierarchy between people who code in C++ or Java and people who write HTML. What I consider the interesting issue is how spreadsheets have been so successful for solving problems that would otherwise require "programming", and make the power of computers available to a much wider audience. Why haven't more systems caught on that would let people solve problems without "programming"?
