I don't think of snowshoeing as an activity in itself, just as the proper footgear for winter hiking (unless you need crampons instead). Modern snowshoes are really very easy to use (compared to flat 13x23 inch bearpaws) and most have built-in traction devices. Hiking on an already-packed trail is a synch - just avoid stepping on your own snowshoes. If you are packing a new trail with a group on relatively level terrain, the followers should step in the spots not stepped in by the leaders to make a broad evenly-compressed path. Breaking trail is exhausting, so best done with a group where everyone rotates the lead position (just like a paceline). If breaking trail on steep terrain, everyone should use the same footprints and attempt to keep them level like stairsteps. On gentle slopes where your shoes may tend to slip, keep weight on your heel to provide better traction (good achilles tendon exercise). Most people probably use ski poles or something similar for balance while snowshoeing, expecially in deep unbroken snow.
