Ask HN: Deep technical forum community to follow

Hi HN,

I believe that most of the programmer, when they where learning, used to hang out in some online community where they asked the most basic question about code, loops, etc...

Of course such communities start to get boring after you have learn your skill and when there are already other skillfull programmers to lead the younger.

Now that we are grew up, what communities are worth following ?

I am looking for some project/language agnostic community where to discuss deep and wide topics about code...

Any ideas ?

(Other than HN, of course...)
