From reading the Post, it looks like 3 things need to happen (at the least)

1. @konijn Bot needs to be reactivated to keep the JavaScript Zombies from overtaking Code Review again

2. The Java People need to take some time to learn a couple of other languages
 - C#
 - Python

3. **< joking >** find a way to hide [tag:php] and keep that junk off our site **< /joking >**

---

Seriously though, it looks like we should all take some time to look through the unanswered questions and see if we can make out some things from other languages, even if it is just to activate users that asked a single question and then lost faith in Code Review in a time before the Great Revival.
