I'll fire up a tutorial on something and 20 minutes into this and I'm all "yeah this does what it says, but it can't be used to do almost anything else..." and I fear the actual person doing the tutorial doesn't know.
Heck I've commented on some Medium blogs where they mention how to do a thing and I'm 100% sure in any real world that code won't do the thing. I post and ask about some aspect of it and the blog author ... doesn't know.
Like outside this one off tutorial and everything working perfectly ... the code is useless.
There's valid reasons to simply code for illustration, but at the same time, without exposing even how to handle an error... what have you really taught someone?
I just hang onto some snippets I like and pick a framework most of the time.
Unfortunately, signaling games are difficult to avoid in any burgeoning ecosystem. The problem is that our signaling schemes are almost as crude as “spray and pray” and our information seeking methods are as crude as “click and pray” (to the search overlords, or to the algorithmic feed overlords).
Both sensitivity and specificity are increasingly impoverished in online information communication. Maybe this is a fundamental caveat to large one-size-fits-all platforms... they cannot serve a variety of needs beyond a simplified representative.
If you're looking to self promote, you can either target the larger audience base of beginner content, or provide domain expertise with advanced topics.... with the gap in the middle then being underrepresented
