It could just be a very advanced case of sir jOhns problem, an almost complete keyboard failure. He's trying to say more, but the letters just aren't there.

Either that or Gluon is chasing the spare letters round Sagittariaus gamma ultra ( I'm not looking up ASCII for greek letters), and they'll turn up as a dribble of slightly chewed characters, scatterd back and forth across a number of years. The blank posts are just the spaces getting back first, as they're fastest.
