Twitter definitely enhances my views as well as my faves. In fact, more than not, when I see "Darn, there's no activity," in the Your Shop section of my Activity Feed, I hop tpo it and retweet some items, and sooner or later the faves start to materialize again.
There's nothing wrong with faves, mo matter who clicks on the little hearts, because each fave appears in different people's Activity Feeds. In other words, it's a good way to get the word out about our items.
Lately I've noticed an increase in shoppers (as opposed to Shop owners) favorite'ing my stuff and/or my Shop. I feel more encouraged about those faves than sellers' faves, since there could be greater likelihood of shoppers eventually buying something. I know I fave mostly because I like something I see.
