I've wondered about this too with my own articles. Admittedly, most of my stuff are stories and I have no more intent than to make the reader laugh, or at least appreciate the satire. There are times I kind of wish people would catch the point of the satire and comment accordingly, but again, since putting a smile on their faces (even if i don't get to see it) is the goal, so comments are appreciated, but not expected.
On the other hand, I do figure some of my articles would generate some response, but even though there are some pretty cool number of hits, 4 or 5 is normal, and 20 is the most I can expect.
Either way, good question and great article!!
