The idea is to have a timeline bar that is inherent in any given digital context. The timelines shows temporal dimension data when needed, to provide the useful context.
The timeline dropdown would drop down like a 100% wide by 250px tall div at the top of the screen that shows the currently article in the present context.
Based on optional keyword, author, and datetime range filters, the timeline would zoom and adjust.
The purpose of the timeline is to show the evolution of stories over time. Nothing happens without context. Yet, in the web, we're often relegated to single URL's the context that the site itself provides. We can do better.
