Audrey Watters poses the question: what’s the best way to save and share with others?
To help facilitate answers, she establishes the following criteria:
Reliability: can you count on this service being responsive? Can you count on it being here tomorrow? 24-7? A year from now?
Data portability: can you get your (students‘) data out?
Privacy: do you (and/or your students) have control over who sees your (students’) data? Can you manage who sees what?
Filtering: do you have to battle schools’ Web filters in order to access the site?
Extensibility: is this a tech platform onto which other apps can build/connect? (i.e. is there an API?)
Forces of habit: what will people actually use?
