Conversation Killer

After three non-university-backed studies and nearly twenty interviews, linguists from the farthest reaches of Nevada, North Dakota and  Mississippi  have come to the conclusion that I ought to be officially categorized into the online/social media "conversation killer" group. I seem to have a knack for posting comments on blogs and Facebook that have a habit of becoming the last comment. Dead last, hence the term conversation killer. What remains a mystery, is why? It's not like I'm always making comments about death, illness, hygiene, taxes, meatloaf, or Justin Bieber.  For anyone interested in proving me wrong, feel free to review any of the post you have made and see how many times other people have posted after me. It's quite impressive, from a pessimistic point of view.
