Generally no, I stay away, but I'll usually not miss more than one week without at least glancing at FT. Rarely do I ever actually post on holiday trips, however. If I note a post where I can perhaps help, I've often emailed the questioner a response.
As letiole notes, in places like Molokai (or Lanai) which are so very quiet, all bets are off however, and I'm more likely to gravitate to FT!
