Historian Marc B. Shapiro writes:
In all the discussions recently about the success of Daf Yomi, I didn’t see anyone note that one of the reasons this success is so surprising is that the whole notion of Daf Yomi goes against what for many years was the outlook of the rabbinic elite. The Shakh, Yoreh Deah 246:5, quoting the Derishah, states that laypeople should not only study Talmud but also halakhah, which he thinks should be their major focus as practical halakhah is שורש ועיקר לתורתינו. It is not hard to understand the point that since a layperson’s time is limited, he will get more out of his learning by focusing on practical material. If, for example, one has an hour a day to learn, what makes more sense: to go through hilkhot Shabbat or to study Talmud? While people today prefer Talmud, the Shakh prefers halakhah, and I don’t know of any rabbinic figures in years past who disagreed with the Shakh. This Shakh is also mentioned in the introduction to the Mishnah Berurah. While it is obvious that one who has time to learn both Talmud and practical halakhah is in the ideal circumstance, how did we get to the situation where those whose time is limited are now encouraged to focus on Talmud? The credit (or blame, depending on your outlook) for this development can, I think, be laid at Artscroll’s door, for Artscroll made learning Talmud exciting for the masses, in a way that halakhah is not, and maybe can never be.
Daf Yomi is so revolutionary precisely due to its democratic ethos, that everyone is welcome to study that which used to be the preserve of only the elites. Much like American universities opened up higher learning to the masses, and created a situation where for the first time in history texts such as Plato and Aristotle were now taught (or spoon-fed) to all, so too, for he first time in history, Daf Yomi allowed Talmud to become a product of mass consumption.
