I really do think we've just been talking past each other. When something is as obviously "tongue-in-cheek" as the original post, I find it funny when people (a) get the joke, then (b) play it with a completely straight bat. It appears that doesn't cross cultural boundaries in the way I thought it would.
You're not alone ... some of my comments are getting significant numbers of downvotes.
<shrug> ... "Humour".
I'll go back to appearing humourless and commenting purely technically on purely technical things. Meanwhile ... nice to connect with you ... thanks for the responses.
I appreciate the feedback ... I think the best thing for me is just not to try again, and to be explicit when I know something is a joke, and clear that I'm adding factual information.
Watching people continue to downvote the comments I've made, HN is clearly the wrong place for me to do otherwise.
