Could it be as Ladislaus said; that SJB is a BOD troll? Look at his posting history, hundreds of one sentence postings with no content.
I'd suggest that one be careful not to loose too much time responding to his postings, and instead take the lead and post informative educational material of your choosing. Let him follow, and ignore his static, or use it as an opportunity to post good material, however, always taking the lead.
For me, he rarely says anything of value, it's not worth my time sifting through his inane static to find something once in a while. I just put him on HIDE. Same goes for Lover of Truth, except he is the opposite of SJB in that he posts volumes! Out of sight is out of mind.
