When a post goes live, notify users who touched it

Encourage them to share/retweet/reshare it.

'touch' is any operation including just clicked through to read, voted, wrote headline (even one that didn't 'win'), etc

Just trying to think this through a bit here:

Somewhat dependent on #12

As an additional prerequisite, we'll need the concept of a notification and a delivery mechanism for users.

To make this easier, we can introduce the concept of an Interaction which has a polymorphic association to an item (content or link) and a polymorphic association to an action (click, submission, like). This would store some redundant data, so I'm not completely sold on the idea. Alternatively, we could have a class that's just responsible for identifying what people have interacted with the content that was posted either directly or indirectly via it's associated link or its other contents and creating appropriate notifications.

Right. My inclination would be to do it the second way but it's not clear that this is the 'right' way to do it. I'm going to ping Nathan on this who might have some ideas about the scalability of each approach.

[peterkinnaird]

Right. The second way seems better to me since it's a separable process, that could be scheduled independently. I'm not really sure though. Pinging Nathan to see if he has ideas about the scalability of either method since they both seem about the same in terms of coding difficulty.
