DAVE GORDON WRITES:
TORONTO — As the rabbi of Congregation Tifereth Beth David Jerusalem in Cote St. Luc, Quebec, 46-year-old Rabbi Chaim Steinmetz not only gives sermons from the bimah, he has also found a way to offer words of wisdom through a virtual pulpit, by blogging.
A blog (short for “web log”) is a regularly updated journal on the Internet where people are invited to comment on entries. Rabbi Steinmetz is one of only a dozen rabbis in North America who have or operate a blog, a handful of them in Canada.
He refers to this ever-growing Internet tool as “the ultimate megaphone.” By opening this digital door, the rabbi has invited people all over the world into his shul, and into his head.
One of the many advantages he cites for having a blog is that his speeches can reach beyond the synagogue bulletin and the Montreal Jewish community.
“In this way, anyone anywhere can see something of interest to them,” he says. “A rabbi gets up on Shabbat, presumably because he has something to say, and on a blog, hopefully a lot more people can take a look at it.”
