popfiend is a prolific poster on LJ, and he adds some valuable content to the material, often having websites or comics that inform or delight. He's often posted wonderful things about his relationship with his wife, and so although we've never met, because of his prose, we felt as though we'd known them well for a very long time. It's hit hard to hear this.
In the Jewish faith, the community gathers around the bereaved, and supports them during the initial week after their loss, and for about a year thereafter, they have special time in each religious service devoted to their mourning. Although we won't be able to cross the continent, our thoughts and prayers go out to the extended family, and we wish them the blessing of good memories.
