I'm not sure "trolling" is fair, but perhaps phrasing your confusion more as "the home page doesn't give me a very clear idea what this is," which is true; the actual front page doesn't mention Smalltalk at all. I suspect that they wrote it with the expectation that nobody just "ends up" on the Pharo web site without having some idea what it is already. Under normal circumstances (e.g., not being linked from the front page of HN) this is probably a reasonable assumption, but it couldn't hurt them to have something like what Squeak.org has: the first full sentence on its home page is "Squeak is an open-source Smalltalk programming system with fast execution environments for all major platforms."
Having said that, how few minutes qualify as "good"? Because if you click "About," that page has a heading that says "Pharo features" whose first bullet point reads "A dynamic, pure object-oriented programming language in the tradition of Smalltalk."
