Question 2 of 6

What does a session look like?

Not “is it a web app.” What is a person actually doing. This is the interaction model. It is allowed to be boring.

They read or watch something you published Essays, docs, a landing page, this site. The bytes go one way.
They fill in or save their own stuff A tracker, a form, notes, a personal dashboard. Other people need not exist.
They touch other people’s stuff Comments, a shared list, a classroom, turn-based anything. Not the same as realtime.
Things happen while nobody is looking Crawlers, agents, bills, nightly digests. Someone still has to run the clock.
It is a conversation with a model A chat UI is still request/response unless you also need a live connection.
