But much more than the names and faces have changed.
This is the dawning of a new day, the entrance of a crew so savvy to 2.0 communications that it's scary.
No wonder so many in the White House press corps seem so pissed. The world is changing around them, like so many bolts of converging lightning, and they don't seem to know how to deal with it.
In a scene that spread with Net alacrity, as Obama paid a visit to the White House corps, Politico reporter Johnathan Martin bypassed the hellos and handshakes of common relations, and went after Obama with a tough question about lobbyists that, under normal circumstances, would have seemed appropriate, but here seemed like a spoiled child demanding a toy.
Obama's coolness in the situation reflected confidence that his people have things under control, on the communications front.
The new White House website is an amazing display of IT talent, to be expected, we suppose, of those who took the Net, along with cell phones and Twitter, to political heights that Howard Dean's folks five years ago never imagined.
The web site offers so much information -- for sure partisan, in all meaningful senses of the word, but, grief, lots and lots of information -- that the routines of reporters there will surely have to undergo serious self-examination.
It makes the sites of local elected officials in New York seem like old one page, paper press releases.
Seriously, we (and I mean Huffington, Politicker, Politico, AfroNetizen, BrooklynRon and many, many other journalist/web sites and bloggers) have to come up with new chairs and whips to handle the new political lion.
The words of Mark Knopfler in his song "Boom, Like That" come to mind:
"These boys have got this down,
Ought to be one of these in every town.
These boys have got the touch.
It's clean as a whistle
And it don't cost much."
Knopfler was singing of the rise of Ray Kroc, late founder of the McDonald's fast good chain. But he just as well may have been singing an ode to the Netizens of the Obama White House.
For the heck of it, maybe you'd just want to see and hear Knopfler doing the above tune, which, we warn you, is a little eerie in chord arrangement and other ways.
