Corresponding task from "add a link": T277356: Add a link: experiment
When we first deploy "add an image", we want to deploy it with a controlled experiment, somewhat similarly to "add a link". But the experiment will only happen amongst mobile users. Here are the details:
- With the advent of the images experiment, we want to end the link experiment.
- Ending the link experiment means making it so that all legacy accounts with Growth features and all future accounts with Growth features have this situation:
- Replace the unstructured link task with the structured one. It will no longer be possible to do the unstructured one, though it can remain configurable in community configuration, in case a wiki wants to switch back.
- If a wiki never had the unstructured link task because they had no applicable templates, then they should still get the structured one added.
- Legacy users difficulty filter settings should not be changed, but new accounts should get the easy tasks by default ("copyedit" and "add a link").
- We could either choose a date to end the link experiment across all wikis, before we start the image experiment. Or we could end the link experiment as part of turning on the images experiment wiki by wiki. This can be up to engineers.
- Ending the link experiment means making it so that all legacy accounts with Growth features and all future accounts with Growth features have this situation:
- For the image experiment, these are the groups that should be applied for account creations after the experiment starts:
- Mobile A: these users created their account on mobile. They get "add an image" on as the only default task. (40% of mobile account creations). This is the only group that will have access to "add an image" at all. Some of these users may subsequently visit their homepage on desktop. See this task about how we will prevent them from using "add an image" on desktop: T295000: Add an image: prevent desktop usage
- Mobile B: these users created their account on mobile. They have the default suggested edits experience without "add an image" in their difficulty filters at all. Their experience would include copyedit and "add a link" as their default tasks. (40% of mobile account creations)
- Mobile C: these users created their account on mobile. They don't get the Growth features at all and are our usual control group. (20% of mobile account creations)
- Desktop B: these users created their account on desktop. They have the default suggested edits experience without "add an image" in their difficulty filters at all. Their experience would include copyedit and "add a link" as their default tasks. (80% of desktop account creations)
- Desktop C: these users created their account on desktop. They don't get the Growth features at all and are our usual control group. (20% of desktop account creations)
- For accounts created before the experiment starts, "add an image" should not be added as a new task type. This is actually different than "add a link", where we did add it for legacy accounts.
