What makes you think this comment is doing anything except providing positive feedback?
>It seems pretty obvious that the author doesn't intend to coerce anyone into doing anything.
Subtext is weird and dangerous. Using more accurate phrasing costs nothing and potentially averts problems.
It doesn't address any of the points mentioned in the article, and in fact, doesn't address the general theme of the article.
There is no subtext at all, the article is simple and clear, and one would be hard pressed to think that the author is trying to force anyone to do anything while reading it.
The author did actually rename it now that it suddenly has a much wider audience! It's now "Open source projects: consider running office hours"
Given that, I think we can safely assume his original audience (blog regulars) didn't mind the title. I realize accuracy is only a small effort, but it IS an effort. Why spend more time on it than is necessary for the audience?
