Alicia's Poem is not brand new quest, but it has been added through gameplay and it's on place where players are going rarely at higher level.  And it's worth of nothing because it's one from "memorials" for real people included in game. And also because the poem is really touching.

Dak Krause died of leukemia in August 2007, Until then he was playing his toon named Caylee with pet Dusky (more info). Now you can do him a honor and deliver poem to Shattrath where he, and his pet, now resides forever. He can be found at Aldor's place, but anybody can finish this quest as he belongs to Darnassus faction.

First of all, original poem ("'Do Not Stand at My Grave and Weep'", probably from Mary Elizabeth Frye, 1904-2004, is the author):

Do not stand at my grave and weep,
I am not there, I do not sleep.
I am in a thousand winds that blow,
I am the softly falling snow.
I am the gentle showers of rain,
I am the fields of ripening grain.
I am in the morning hush,
I am in the graceful rush
Of beautiful birds in circling flight,
I am the starshine of the night.
I am in the flowers that bloom,
I am in a quiet room.
I am in the birds that sing,
I am in each lovely thing.
Do not stand at my grave and cry,
I am not there. I do not die.

And now the WOW version. Really nicely re-written.

Do not stand at my grave and weep.
I am not there, im dont sleep.

I am in a thousand winds that blow,
across Northrend's bright and shining snow.

I am the gentle showers of rain,
on Westfall's fields of golden rain.

I am in the morning hush,
of Stranglethorn's jungle, green and lush.

I am in the drums loud and grand,
the thundeorous hooves across Nagrand.

I am the stars warmly gleaming,
over Darnassus softly dreaming.

I am in the birds that sing,
i am in each lovely thing.

Do not stand at my grave and cry,
I am not there. I do not die.
