I did this one during a class on post-structuralism.
This does not get at the core of the textual critical movement of post-structuralism. In my understanding, post-structuralism is about meaning being located in the mind of the reader rather than the author (or the text itself). So in this case, I think the author’s (post maker’s) reading of his work or his experience of the work is the real truth encounter. An alternative reading is that he is just a guy making posts who doesn’t care what other people think. I guess its up to the reader to decide where the meaning of this post is located.
