Sharing frequent or even weekly community updates is a best practice of Mozilla and OpenStreetMap.  You can help shape these. Just send a note to hleson@ushahidi.com to add items. Posts usually go up on Wednesdays or Thursdays of a given week.  

NOTE: Weekly and community updates are posted on the blog. Search #weekly. We will no longer duplicate these reports on the wiki.
