After enduring the infamous Rabbi Wasserman anti-zumba video debacle I am convinced that I am living in the coolest era. Now that there are shiurim are available online the rabbis who post them are going to have to pay attention to their online image. Before online shiurim a rabbi could only make a fool of himself in front of those who were in the classroom or perhaps whoever taped the shiur and lent it to a friend , now he can make a fool of himself in front of anyone with online access.Of course this could also mean that many rabbis won't allow their shiurim online for this very reason . I think that having shiurim online will encourage rabbis to actually pay more attention to what they say because if its posted online they will be held more accountable for what they are preaching. This actually is a good thing even though I am sure others will disagree. I think that online shiurim will give rabbis the opportunity to elevate shmiras halashon to the fullest extent which truly will be amazing. One can only hope.
