SFist has, for the most part, spared you any vile "baby bump" talk during Jennifer Siebel-Newsom's pregnancy. But now that SF Mayor Gavin Newsom and Jen Jen are first-time parents -- Jennifer had a c-section a little after 12:30 p.m. today -- everyone online is abuzz -- yes, abuzz -- about it.

Here's what people are saying. Ahem:

7x7's Catherine Bigelow: "Not surprisingly, the 'revolution' was Twitter-ized by the proud, but nervous, papa to his more than one million 'followers.'"

Eve Batey at SF Appeal: "Jennifer Siebel, the mother-to-be, was not due until next week, but (speaking as someone who was pregnant in summer heat herself) given the weather report for next week, Baby girl Newsom's timing couldn't have been better"

N Judah Chronicle's Greg Dewar: "OMG that is the name they picked? Awesome."

Valleywag's Ryan Tate: "Gavin Newsom, the heavily-lacquered lefty-sun-God mayor of San Francisco, has the most progressive technological track record of any California gubernatorial candidate..."

SFGate: "New daddy tweeting again."

SFBG: "Gavin tweets, while Jennifer gives birth?"

NBC Bay Area: "[Newsom] turned to his closest Twitter friends for advice on diapers and feeding."

laughingsquid: "congratulations @GavinNewsom on the birth of your baby girl"

brochtrup (AKA Brock Keeling) "@gavinnewsom get yourself some Yo Gabba Gabba! dvds at once. babies mainline the stuff."

Gavin Newsom: ""Jen is doing great.. Not sure she is happy I am on Twitter."
