What's making me happy this week:
1. A recent entry in the Mozilla Blog discussed the possible value of anonymity in decreasing bias in code review processes: https://blog.mozilla.org/blog/2018/03/08/gender-bias-code-reviews/
2. The opt-in "pingback" telemetry from MediaWiki installations, which is available since March 2017, suggests that there are more than 40,000 unique installations. See: https://pingback.wmflabs.org, https://www.mediawiki.org/wiki/Manual:$wgPingback and https://wikimediafoundation.org/wiki/MediaWiki_Pingback_Privacy_Statement.
There is also some news which is a little older and I am now getting around to sharing here:
3. A research project has been started which aims to test whether vandal activity can be detected in (near) real time, which may open opportunities for interventions earlier in the process of publishing edits. See https://lists.wikimedia.org/pipermail/ai/2018-January/000221.html.
