Well written Ryan. You've raised a couple of good points(community, user experience, career notice) and it makes sense to focus on a blog that allows sharing with the right audience.
Medium has been particularly difficult at times especially when it comes to displaying things like code snippets in a way that's readable. I've ended up creating GitHub gists and linking to them, which takes extra time bouncing back and forth. Also submitting articles for publications can take a while before they see the light of day.
I'll be considering the switch a bit more in the coming months.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
