Tonight we will be concluding massechet eruvin in Daf Yomi. It is about time. The attrition rate was very high because eruvin is so hard and complicated. It was so hard that Meorot (major pushers of Daf Yomi shiurim in Israel) even rented the International Conference Center (Binyanei Ha'Uma) in jerusalem and made a big event of the siyum the other day, as a way of trying to get people back and motivated to start the new tractate of Pesachim..
No matter how complicated it was, one has to really appreciate the last 6 or 7 daf.
