There are three buttons that act as sorting directions at the top of the answers section: "Votes," "Oldest," and "Active." The "Active" option sorts by most recently modified, which is _usually_ what you'd want instead of strictly newest. (i.e. an edit would update the timestamp, making that answer have a more recent activity date)

So, I guess the answer to your question of "why can't I" is "good news! you can" :)

Well, none of those options do what I want.

More often than not, sorting by "Active", "Oldest" and "Votes" usually surface the same 2 or 3 answers, and I still need to scroll down to the bottom to find out the most recently posted answer that has more up to date info.

I don't see why I shouldn't have the choice to sort by "Reverse Oldest" if you will, when it's so useful a lot of the time.

This is why Stack Overflow has just started the "Outdated Answers project" in which users can set answers as outdated: https://meta.stackoverflow.com/questions/405302/introducing-...

I always thought the should have a language version. Eg python3, php7. JavaScript es6....

Tags work to categorize by language (https://stackoverflow.com/questions/tagged/python-3.x); by having multiple languages on one site, you'll have a broader audience because there's few developers that only work with one singular language.

> If I search for something related to javascript for example

As someone that's been learning a little JS over the last year, I quickly came to the realization that you skip over the SO links that come up in the search, and you go to one of the many other sites. I've had good luck with w3schools and mdn. SO is a lost cause for JS.

I agree.

However sometimes I am looking for some error related to a botched nodejs install for example, or something that has to do with permissions being set incorrectly and other stuff that does not live in MDN and other documentation sources.

For the actual language questions I do go directly to MDN instead.
