Many experienced Wikipedians use their watchlist as the place they go to see what needs their attention on Wikipedia. For newcomers, such an activity feed might be beneficial to them because it would show them that interesting activity is happening and that the wiki is a lively place to join in. The problem is that newcomers do not have watchlists, since they have not made any edits. This module would be a way for newcomers to begin to see wiki activity that is interesting to them, and to begin to build their watchlist.
This module may integrate with newcomer tasks, since doing a newcomer task is a way to join in the activity being shown in the watchlist.
