I remember vaguely we tried some sort of "wikipedia newspaper" some time
ago, but it didn't work. Today I saw a similar attempt on the German 'pedia,
where you should add today's date each day on a special page and write about
current events from the news.
This might actually work on
wikipedia.com, if we'd automatically add a link
to "today" (like [[2002-03-22]]) in the sidebar. It would draw attention and
remind people there's something they might want to write about. That way,
we'd get at least links to many current topics, and on wikipedia, links tend
to turn into articles ;)
