Q: Why do github.io (and others) only host static pages?
Multi-user interaction
"Chat room" model
Socket connection established for each site visitor
Any messages server receives, are 'broadcast' to all other sockets.
Sockets
Socket enables real-time two-way communication
Each client gets a different socket number, or "id" to use once the connection is established.
