ANY free exposure is a good thing. It clutters my feed too...but think about it this way...person A has fav'd your shop, but only has 1 person in their circle. You list an item. Person A gets to see that item because they fav'd you. ONE other person also sees that item. Now take Person B, who has also fav'd your shop but is involved in 2000 circles...how many people do you think see your just listed item???? This is my understanding of the way it works...and so it is a combo of your shop/item being fav'd and the # of circles you are participating in...
please someone correct me if I am wrong...
i also took a long time to enter the circling thing, but i do see it's advantages
