From today’s New York Times:

Yes, journalism is a matter of gravity. It’s more fashionable to denigrate than praise the media these days. In the 24/7 howl of partisan pontification, and the scarcely less-constant death knell din surrounding the press, a basic truth gets lost: that to be a journalist is to bear witness.
The rest is no more than ornamentation.
To bear witness means being there — and that’s not free. No search engine gives you the smell of a crime, the tremor in the air, the eyes that smolder, or the cadence of a scream.
No news aggregator tells of the ravaged city exhaling in the dusk, nor summons the defiant cries that rise into the night. No miracle of technology renders the lip-drying taste of fear. No algorithm captures the hush of dignity, nor evokes the adrenalin rush of courage coalescing, nor traces the fresh raw line of a welt.

And the most important part of who will bear witness in the future:

Of course, Iranians have borne witness — with cellphone video images, with photographs, through Twitter and other forms of social networking — and have thereby amassed an ineffaceable global indictment of the usurpers of June 12.
Never again will Ahmadinejad speak of justice without being undone by the Neda Effect — the image of eyes blanking, life abating and blood blotching across the face of Neda Agha-Soltan.

I’m not sure that one reporter will ever hold the same power as the masses in the new media landscape.
