*Conference*
The 2018 Wikimedia Conference https://meta.wikimedia.org/wiki/Wikimedia_Conference_2018 starts this week in Germany. The core conference will occur from the 20th through the 22nd.
*WMF Research Showcase*
On Wednesday, the WMF Research Showcase https://www.mediawiki.org/wiki/Wikimedia_Research/Showcase#April_2018 will include presentations on two subjects that I think will interest a number of Wikipedians:
1. "The Critical Relationship of Volunteer Created Wikipedia Content to Large-Scale Online Communities"
2. "The Rise and Decline of an Open Collaboration System, a Closer Look"
*Photography* As often happens, Wikimedia Commons contributors have selected some great pictures of the day for this month https://commons.wikimedia.org/wiki/Template:Potd/2018-04. Here are a few examples:
