riddle - Hearken, now, and listen close!

Hearken, now, and listen close; I have so much to tell.
Now lend an ear and do your job; you surely will excel.
To find my hidden message, gaze on every word herein.
While skimming through it might be fast, you'll miss the quiet gem.

How vitally important are the details of this verse;
examining them closely is the task to take on first.
And once they've been digested, one may feel the need to snooze;

now please reject that feeling and keep minding p's and q's.

Time and time again, you need to squelch the urge to rush.
I know that if you get too lax, you'll miss some clues and such.
So look at each word carefully; just read them one-by-one.
My friend, if every word's perused, your work is almost done!

I know that all this vigilance may start to vex or chafe.
So here's a hint to help you out and keep you feeling safe:
Some people say that punctuation rules are absolute.
Ill-use of them is abject and quite low, there's no dispute.

Now, as you keep perusing, you may find a common theme.

Getting down and dirty is the answer, it may seem.
Find every hidden message in the fine points of the text.
Rush to do your job, and quiz specific aspects next.

Oh, lazy folk will squawk at grammar law misapplication,
giving strong opinions of strict laws of punctuation.
Many nix all joy in words, subscribing to this faction;
in point of fact you might say it's a capital infraction.

Every word's important in this lengthy, rambling prose.
Altering just one could lose the message that's enclosed;
please examine hard and quick the verbiage herein.

'Cause every word's important to the puzzle that it's in.

Here's the quest that's put before you, puzzler and chum:
locate the mystery unknown; to languor don't succumb.
Search through all the text to see what's shrouded here among
the words you may enjoy or may prefer to leave unsung.

Thus far, you'll think not much was said about this work's solution;
so you'll obtain it straight right now, without any dilution:
you want a pair of words portraying you, my puzzling buddy!
And no quick fix can find it! No, just vim and lots of study!

Zest is what you'll have to have as these two words you seek;

as said before, the phrase describes a quirky puzzle geek;
just make a guess, go check your work; you'll see if it is right;
for after all, it's sure that you'll excel; you're very bright!

As fin'lly this verbose creation's coming to a close,
please acquiesce to take my thanks for suff'ring through my prose --
my urge to wax poetic may be tiresome to some,
but still, it's rather jazzy, if your brain is not yet numb.

What two-word phrase is hidden in the poem above?

Answer

The two word phrase hidden quite cleverly in this long passage is

PUZZLE FIEND.

Which I reckon I am! :-D

This word was hidden in this puzzle in the following way:

In each stanza of four lines, all the letters of the alphabet are present, except one. In the first, P is missing. In the second, U is missing. Continuing to determine each missing letter gave me the string PUZZLEFIEND. It was easy to figure out the phrase PUZZLE FIEND from that.

The lines that gave it away were

In the third stanza:

So look at each word carefully; just read them one-by-one.
My friend, if every word's perused, your work is almost done!

And in the seventh stanza:

Every word's important in this lengthy, rambling prose.
Altering just one could lose the message that's enclosed;

An additional hint that I missed. Thanks Sabre for finding the clue that was craftily embedded into the puzzle

The "capital infraction" phrase in the puzzle was a big giveaway. All the capitalized letters in the puzzle spell out HINT WHAT IS MISSING FROM EACH STANZA.
