-## Feedback?
-
-Turning this into a SaaS project would be interesting.  A simple setup
-would be very straight-forward to implement, however at a larger scale
-it would get more interesting:
-
-* Assume two people have subscribed to the same feed.
-   * But they did so a few days apart.
-* That means what is "new" to each of them differs.
-   * So you need to keep track of "seen" vs. "new" on a per-user __and__ per-feed basis.
-
-Anyway it would be fun to implement, but I'm not sure there is a decent
-revenue model out there for it.  Especially when you can wire up [IFTTT](https://ifttt.com/) or [similar](https://zapier.com/apps/rss/integrations/webhook/1746/send-a-webhook-when-an-rss-feed-is-updated) system to do the same thing.
