Devrel Is a Party (no it's not)

I’ve been interviewing a lot lately (and no, I don’t want to talk about it). I’m asked almost all the time “How do you define Developer Relations?” and this post is the long-form answer to that question. I’m writing it because almost every interviewer I’ve given this to has said some form of “that’s a really good analogy! You should write that up as a blog post.” So here we are.

Measuring and Monitoring Community Engagement on Discourse with InfluxDB

This post was originally published on InfluxData’s Blog Monitoring Discourse We here at InfluxData use Discourse for our Community (you’re a member of our Community, right? No? Well, go sign up!!) Part of my job here at InfluxData is to keep my eye on the community, answer questions, and work to grow the community. And part of that, of course, is metrics. It always comes down to what you can measure, doesn’t it?
