Discourse has a great system of subscribing to the categories and tags one is interested in – which will then result in getting e-mail notifications when a new topic (or new post, depending on the setting) is added to a category or tag.
However, people here don’t really use this system. I just had a look at the numbers, and:
only 55 users subscribed to categories , of which 40 only subscribed to one or two
Our current maze of tags is certainly not inviting to subscribe. But still, these numbers are incredibly low. It seems people don’t know about this aspect of Discourse. This basically means there is currently little way for people to be notified about potentially relevant topics, resulting in lower-than-optimal engagement.
So how would you imagine notifications to work ideally? I can then try to map it to the existing Discourse features (subscribe-by-default categories and tags, topic invites and mentions, digest e-mails). One of the most elegant ways might be to derive who should talk to whom next automatically from Graphryder data and then sending topic invites automatically (which might be a discussion of interest to @hugi and @alberto).
