I know fuck-all about programming but I think a useful implementation of nostr would be a mechanism that notifies you if a mutual has posted an event commenting/reviewing a particular brand/product/service you are shopping for.

For example, if I go to XYZcoffee and Joe Shmoe is a mutual who has previously posted saying "that brand sucks" I would get a browser notification displaying his review.

Is such a thing feasible?
