Many products depend on community, on adoption within a tribe, on buzz--these products aren't viable when they first launch, precisely because they haven't been adopted. "Being used by my peers," is a key element of what makes something like a fax machine a viable product, and of course, your new tool isn't.
With enough patience and push and consistent enthusiasm, these products have a shot at crossing the threshhold. But if the mindset is "see what works and do it more," you'll often discover yourself giving up long before that happens.
Very relevant to the Snowball initiative.
