We don't know exactly what's going to happen with Tab Center--or any of these experiments--in the long run. Our goal here is to get feedback from our users to drive successive UX and engineering iterations.

Once experiments have incubated in Test Pilot for awhile, we will have a number of options depending on each experiment's overall success. We may push them over to AMO, or integrate them directly into the browser. If an experiment is really unsuccessful, we may simply cut our losses and walk away. Test Pilot should help us make these decisions more quickly and effectively.

We'll be blogging more about the overall Test Pilot pipeline in the weeks to come. Stay tuned!
