Specifically, we’ve taken a number of steps to try to make it less intimidating to post to New to Julia. The category name itself was actually changed in response to such a suggestion! We’ve also iteratively changed some of the messaging around the site itself with that very goal in mind, and can definitely continue improving. I also often try to calibrate my responses based upon the category — an Internals & Design topic is very different from a New to Julia one — and I have sporadically encouraged folks to do similarly (as have others).
Please don’t hesitate to make suggestions over in the Meta Discussion, and that category description is a wiki so Regulars can even improve it directly!
