Problems
|
|
1. Can't delete, very annoying
|
|
Tombstones. Send all IDs and all Tombstones. Ask only for posts that we don't get a tombstone for. Don't send posts we have a tombstone for?
|
|
|
|
Posts don't propagate, you need to refresh to see new posts.
|
|
Broadcast when we post to all peers we know about.
|
|
|
|
3. Posting is slow because too long to render
|
|
2. Can't follow people
|
|
4. Can't like or reply to posts
|

Restruucture the app around the data. App/WS split is messy. Clean it up.
