PSA: Make sure blog post images are optimized!
https://about.gitlab.com/2017/05/16/devops-containers-gitlab-openshift/ has a 7.1MB cover image. Way too big! Make sure to get it well below 5MB, then use https://tinypng.com/ to optimize further.
It would be cool if there was a spec for this. All images should be at least smaller than 1MB. The more huge images we have, the slower the website will be.
