I created TR-NewsWall. What you need to know:
- It can combine Twitter + RSS + Instagram feeds into a single timeline.
- Has the ability to deliver "breaking news" as quickly as possible.
- Decouples the user from online tracking.
- Is implemented as a single binary server for RPi (~75 MB RAM).
- Works with practically all client devices (landscape + portrait).
- I think it is pretty. It doesn't feel like using an office/spreadsheet app.
