I think StackOverflow was awesome when it started (and several years later still is) but over then it had failed to innovate / grow.
There has been attempts to create products like SO documentation, and SO jobs (and now SO teams) but they are not aligned with what made SO good in the first place. ¿What is the one thing SO was meat to solve in the first place?
This is was Jeff Atwood wrote when it was launched:

Stackoverflow is sort of like the anti-experts-exchange (minus the nausea-inducing sleaze and quasi-legal search engine gaming) meets wikipedia meets programming reddit. It is by programmers, for programmers, with the ultimate intent of collectively increasing the sum total of good programming knowledge in the world. No matter what programming language you use, or what operating system you call home. Better programming is our goal.
It was created to go against paid to question sites and to get the best from sites like wikipedia / reddit / blogs / forums.
To grow, SO has to go back to think what's the thing most frustrates developers while looking for information and work on that.
I understand there's the pressure to run a business too but there's also the possibility for Stackoverflow to become THE developer hub it was meant to be. I would expect 10 years after launching Stackoverflow to be organizing all the developer conferences in the world, that all the documentation of any API / framework was available in Stackoverflow (doc was in the right direction but I get it was hard to maintain) and that anyone that has something to do with development had to come to stackoverflow to learn more about it.
Example: X organization (Microsoft, Google, Facebook, Amazon, Tesla any) announces a Y (framework, product, language, compiler, technology) I would expect anyone interested would run to stackoveflow to learn more about it, and then when trying to do some examples I would go to SO again for reference, examples etc. I don't know what does that product look like, it's definitely not a forums site and not necessarily what SO is today (although is very similar) but I would love to see it.
Keep the good work!
