Brainstorm secure ways to share data

ActivityRecommender currently doesn't use the internet because that makes it easier for users to verify that their data isn't being sent anywhere.

However, it might be nice for users to be able:

• to share parts of their activity graphs with other users to help them get ideas
• to share specific protoactivities with others to help them prioritize
• to share recommendations with others so the two of them can do something together

It could be interesting to brainstorm ways that ActivityRecommender could use the internet and still allow users to be confident that ActivityRecommender is only sending the information it is supposed to be sending

One idea: ActivityRecommender could export a different type of shareable data file that could be imported and exported by users, and which a user has the opportunity to inspect before they export it.

That would provide clarity about what is being transferred; hopefully it wouldn't be too much trouble for users
