I’ve been experimenting over the past couple of months with building a system that combines:

• a shared photo grid (users can contribute simultaneously),
• group chats and announcements,
• and event checklists.

From a programming perspective, I ran into a few interesting challenges:

• Handling real-time synchronization between photos and chat without overloading the client.
• Designing an efficient data model for a grid that multiple users update concurrently.
• Balancing flexibility (anyone can add) with structure (organized tasks/events).

Curious how others here would approach these kinds of trade-offs.
Would you use CRDTs, OT, or some other approach for the real-time sync?
