I am building Postmob as an alternative timeline interface. Not because time is irrelevant, but because time alone has become too weak as the primary structure for reading what people think.
A timeline is useful when the question is what happened next. It becomes less useful when the question is what this is connected to, what changed, what it depends on, or what someone is trying to continue.
Before Postmob, I worked on Flint, a startup built around a similar conviction. Flint did not survive as a company, but the problem stayed alive. The interface was never just about arranging posts. It was about whether relation could become something a person could actually read.
Postmob starts from the smaller claim that posts should not only appear after one another. They should be able to point, answer, branch, return, and still remain legible on a screen.
The hard part is not drawing a graph. The hard part is making structure feel ordinary enough that people can use it before they have to explain why it matters.
Postmob is currently in closed beta. If this is a problem you already feel in feeds, threads, notes, or research, write to hello@postmob.net.
