There's been a few different cases of excellent writing I've seen lately that all fit into the profound / important category.
Most recent was an e-mail from CNN Journalist Anderson Cooper that he allowed to be posted online. From Andrew Sullivan's news site The Daily Beast, Anderson Cooper: "The Fact Is, I'm Gay" features a very well written note from Cooper that concludes with "I still consider myself a reserved person and I hope this doesn’t mean an end to a small amount of personal space. But I do think visibility is important, more important than preserving my reporter’s shield of privacy."
On the Fatherhood topic I love to read and post on, a few days ago I came across the piece "Daddy Blues" by Tony Rehagen for Atlanta Magazine. It was very cool writing on something that can be both incredibly rewarding and difficult to deal with.
Finally, a very short piece with heft to it was "Toiling in Obscurity" for the site FlipCollective. Tom Dinard writes in it of a stopping a large display case from falling on a toddler. It's an emotional piece that's made all the more interesting with nobody noticing the lifesaving act made.
