Is it possible that along with the Omer, observance of many mitzvoth has become onerous due to how we practice today? The Omer is counted, depending on one's reading of the text (Chumash) either as an offering (which is no longer done) or today as a method of preparing for the festival of Shavuot, a one day observance which many of us still observe for 2 due to rabbinic dictate. Perhaps this is the problem. Too many rabbis continue to insist that we live our lives as we did in exile, "customs of our fathers," when many of those customs are no longer necessary. Maybe, when we address those issues and others, more people will observe Sfira.
