If you go to /settings/ux, you'll see a few nobs for adjusting your DEV experience, such as fonts (I'm sans-serif all the way!)
One of the settings is "experience level", a self-assigned number to help your feed deliver the most relevant content.
If you're a newbie, set it to 1 or 2, if you're more experienced go 4 or 5.
It's not an exact science, but it will help gently nudge your feed a little bit towards your appropriate level as a developer along with the tags you follow. It's 100% private, so choose the most honest answer.
We have seen improvements to feed relevance and will continue to try to tailor it.
To be clear: this is for your consumption preferences. It will not imply the level you write for. A more experienced developer might write stuff for newbies, and a newbie might write highly-researched content that is best suited for experienced developers.
