But here's a clever idea: The RSVP form allows you to suggest a colleague in your place. It would be a pity if jealous colleagues at, say, the New York Times filled out the form for John Markoff and suggested they attend in his place. I just declined on behalf of AllThingsD's Kara Swisher — though she could always crash as the guest of her wife, Google executive Megan Smith. Here's the full invite:

****CASTRO STREET ELECTION NIGHT COMMUNITY CELEBRATION/PROTEST***
SPREAD WORD!

This evening, Tuesday, November 4th, the eyes of the world will be focused
upon our
community. In recognition of the historic nature of this election, a
community celebration and/or protest will take place, in the Castro.

Weather permitting, election results will be broadcast on a large, out
door, video screen.

DJ's David Harness, Liam Shy, and friends, will be serving up the beats, to
move your feet, should a celebration be in order. Look for us, on Castro
street, between Market and 18th, after dark!

In the words of Donna Summer's most recent track..."Stamp your feet on the
ground, Make it really loud, make the biggest sound, You ain't goin' down!"

There will be no security through the Townsend Center Public Parking delivery access driveway! Walk right in and get on gurp [sic] with the blue button up collared shirt, khaki Dockers crowd balding mid life guys with glasses.

After the jump, our tipster's full guide with illustrations.

From the Townsend side of the block the Concourse Exhibition Center, walk through the Townsend Center Public Parking lot's delivery ramp straight through to the parking lot on the other side of the Parking building.

That parking lot is the auxiliary parking lot of the Concourse Exhibition Center is where the Cisco Dev Conference Party overflows with the 'Sports' and 'Games' section of their themed party reside.

There will only be security on the 7th and 8th street sides of the party, as well at the Concourse Exhibition Center door.

Of course, in publishing this we could ruin it for everybody. But if there's a lesson to be learned here for future reference, it's that walking through a connected parking garage is often a fine way to find a back door. Dress the part and complain you lost your badge in case anyone asks.

6:52pm PST Room is packed to capacity.

6:53 Cyan [Banister, founder of Zivity]: Her hope is that this event creates more engineers.

7:00 Any kerfuffling about porn has mellowed into a slideshow about the Facebook platform API. Just like any typical tech networking event, a pitch is difficult to sex up, and that's just fine.

7:14 If anything, there's likely more porn talk going on across town at the "Girl Geek Revolution" counter-event, promoted as a porn-free alternative.

Our eagle-eyed correspondent spots a rare Chanel handbag.

7:18 Ostentatious purses, shiny patent heels in the minority. Most in sweaters, flats and not much Twittering, either.

7:22 For a woman-centric San Francisco event, way more South Asian women than the typical "inclusive" yadda yadda.

7:25 A Cal Berkeley student [Alina Libova] gets applause for selling her Easter Eggs application. Overheard: "At least someone's monetizing."

Easter Eggs Facebook app creator Alina Libova, center, in white blouse.

7:26 Standing room only as the women who worked late pour in.

7:32 Acquisition market for Facebook applications? Easter Egg developers got twenty inquiries after handful of posts on Facebook seeking a sale.

7:39 Male count: twelve.

Zivity's geekification weapons include a "Speak 'N Math."

7:51 Zivity photography in photo booth only, "with a Tie fighter!" Photos will appear on Girl Geek DInners' Facebook group and the Girl Geek site — not on Zivity, Banister assures.

8:12 Postgame talk with Banister: The "Alt" Girl Geek Dinner organizers invited her over, and she looks forward to talking with Mary [Hodder, Dabble founder].

8:17 Also, just saying, no line for the women's room, so save the jokes.

8:38 No one has mentioned the Zivity controversy. I'm almost nervous that I'm putting it in their mouths.

Across from the Girl Geek Dinner, the notorious Market Street Cinema.

8:44 Jessica Santana of [sustainable IT provider] Inveneo had heard word none of porn panic; we talk localization and mobile in dev world instead. Little burgers are little, tasty.

9:11 Megan's out, I'm done tilting at the actual porn theatre across the way. Inside, here, there, it's all just women at work.

9:35 Too late to hit the "Girl Geek Revolution" alt dinner. Still, as my girl Emma Goldman would say, "If I can't make porn, I don't want to be part of your revolution."

Hot air balloon rides and circus performers. But then it would be difficult to fit either into 1015 Folsom, where the party is being held tomorrow night. As for the rest of Bebo's original employees? They've all left already.

But besides the commercial rationale, there's a more disturbing reason for Facebook to throw a prom for its employees. With its cafeterias, gyms, and volleyball courts, Google likes to makes its employees feel like they never left college. Could Facebook be trying to make its workers feel like they never left high school? Infantilization is an effective employee-retention program. But it is not a particularly attractive one.

More pictures from Facebook's prom.

• Fired MySpace exec Shawn Gold moderates a discussion about the Impact of the Social Graph on Search and Discovery, with execs from Mahalo, Eurekster, and some other noname startup. It's in Building 43 on the Googleplex tonight at 6 p.m. [Webguild]
• If you're going to be at the Googleplex anyway, try to crash its Holiday Press soirée, the event from which they disinvited my boss. It's at Slice Cafe at 6 p.m.
• So how did that Stanford class on Facebook applications do? There's a meeting tonight on the Stanford campus to go over the outcome. Our guess: lots of poking. [Eventbrite]
• Spontaneous Drinking Night heads to LaTrappe on Greenwich St. [Facebook]
• Charles River Ventures partner Susan Wu moderates a "SNAP Chat — Finding the Funds" panel on VC Funding tonight at CNET's offices on 2nd St. Hint: Somewhere in the bank. Starts at 7 p.m. [Eventbrite]

Google's reckless hiring over the past year has created a problem for party planners: too many people to fit into one event. So, the festivities have been severed into two days, tonight and tomorrow, with signups on a first-come-first-serve basis. We hear that most of the San Franscisco-based employees are going tonight, because why would you want to travel down the peninsula on a Saturday when you could just stop by right after work?
