It would be great if there was an opt-in setting that would allow for notifications based on learning-based context in addition to more explicit @me notifications. For example, I was a contributor to a large project with many groups participating. I certainly want to receive notifications for actions tagged to me, don't want to be notified of actions involving distant tasks on the project involving another group, but I'd like a feature that enables 'smart notifications' e.g. even though I wasn't explicitly tagged, a task or activity that is likely to involve me for input or approval.
