Spoonbill lets you track changes in someone’s Twitter bio, like this:
Spoonbill’s creator, Justin M. Duke, describes the app, which has nearly 93 thousand users, as a “tracking tool for online metadata.” Over 45K of those users have signed up to receive daily emails that aggregate updates across all the Twitter profiles they follow. The open rate for these daily emails hovers around 55%, well above average for email campaigns.
Never knew so many people would be interested in a service like Spoonbill.
For marketers, it makes sense to observe what popular profiles are doing.
But for regular people, it seems like a new social media addiction.
