As a related attention-focusing change, remove user registration notifications from (the default form of) the "Recent changes" page.
I suspect that this is hard coded actually, as each wiki account has a userpage (User:[username]), which is itself wiki-editable.
How can we incentivize more productive activity on the LW wiki? There are many articles that could be created or expanded.
Are there previous discussions on this?
One suggestion: We could add a "good explanation!" button at the bottom of each article, and every time it is clicked, the user account responsible for the plurality of words in the current draft of the article gets 10 karma points. This requires that LW and LW-wiki accounts be synced, first.
How can this suggestion be improved?
What other suggestions do people have?
