I really hope he stays (though I doubt he will) as it brings a new energy to the board.
Oops, sorry but he/she is taking a short (2 week) holiday. Maybe he/she is tough enough to come back after that short break. The personal abuse thing doesn't work here, even if it's simply a case of someone attempting to "match tones" with antagonists.
My bet, he/she will be back. There's a point to be made.
