A Journey through Known Territory

Question

Our journey begins, right in this place. Here, you will find many logical ace(s).

So... Our next stop, whos title is an exception, there are many people with language connections. Unfortunately, it cannot point you to the next one, but, don't worry! There will be more fun.

We'll descend a generation, to meet this recursive child. But don't be fooled, it's discussions aren't mild!

Next, please meet my numerical friend. We were part of society, beginning to end.

Now I will show you where everything starts. From definition to acquisition, the aliens have big hearts.

Going in to the smaller places, we find place 2's fun brother. They like their answers short and pithy, unlike the others.

I've shown you around, but there are many more. Try them out, they're not a bore; you can even earn a score!

To get your answer accepted, you must have the solution along with the meaning of every line.

Good luck!

That's Stack Overflow - a common error (or "exception") in some programming languages. It doesn't have a list of the Stack Exchange network sites at the bottom.

Seasoned Advice is a child site of Stack Exchange, and it sounds like "see son". Seasonings are meant to make food not mild.

Mathematics.SE, probably?

This is Area 51, where new sites are created, starting at definition and ending at acquisition.

This is Programming Puzzles and Code Golf, whose questions were originally on-topic on Stack Overflow. The goal there is to solve a programming task with a file as short as possible.

There are dozens of other sites on the network, and you can earn reputation on all of them.
