True Ventures, the firm which counts WordPress maker Automattic and tech-blog network GigaOm among its holdings, hosted people at its offices on Pier 38 right by the Bay Bridge. Spotted at the party: GigaOm reporters Katie Fehrenbacher and Liz Gannes in conversation with Richard MacManus of ReadWriteWeb. The effortlessly charming Jared Kopf of AdRoll tried to duck having a specific launch date for his ad software company. (Before December 31, he promised.) On my way out the door, I spied First Round Capital VC Josh Kopelman chatting with angel investor Ron Conway, VC Stewart Alsop, and TeeBeeDee's Robin Wolaner. (I recognized Wolaner because she recently blogged about having eye surgery complete with mid-surgery pictures. Ew! In a Discovery Channel can't-stop-looking sort of way.)

I spoke with Kopelman for a moment as he explained the reason why he tried indoor skydiving — the activity which broke his shoulder. His wife thought it seemed safer than the zero-gravity flights currently in vogue with the Sand Hill set. Oops.

Onto the Rickshaw Stop across town, to a music session for hacks and flacks. The open mike jam session starred jounalist rock star Don Clark of the Wall Street Journal and Kevin Maney of Portfolio. Here's a secret for you — whenever Don Clark plays, a gaggle of PR fans mob the audience. Last night? No different. Spotted in the crowd, flacks from big firms, like Voce Communications, and PR consultants aplenty. Ali Partovi, founder of music application service iLike, came out to support the scene. PR goddess Brooke Hammerling appeared and greeted Le Web 3 conference producer Cathy Brooks effusively.

To SoMa and Fluid for the the last stop of the night, where Mike Jung of Panorama Capital and Eric Chin of Bay Partners brought together alums from their Alpha dinners in Woodside for a drink special. Spotted: First Round Capital director Howard Morgan, who spoke briefly about his investment into the Zero-G airlines. (He's been on three of those flights already!) The crowd was full of founders. Among the crowd were Mint's Aaron Patzer, HotorNot founder James Hong, former Greylock VC turned Chirpscreen founder Eve Phillips and the guy blowing kisses above, PBWiki founder David Weekly. Eric and Mike told me that they aim to have their Alpha dinners bring together founders and VCs with a common thread, with the hopes of making connections that pay off. And it's happened. Oren Michels of Mashery reports that his widget-software startup received a check in the midst of one of the Alpha dinners. The Alpha luck might have struck again. At the end of the night, Mike Jung snuck away for a phone call. Rumor was that a deal was in the works. Heard anything about it? Let us know.

So, what does vodka have to do with tech? Rob Bailey, founder of Delicious Brands, maker of Lotus Vodka, is an ex-Yahoo business-development exec who came up with the idea of creating a vitamin-infused vodka after mixing the spirit with Glacéau Vitamin Water. It's sort of like disintermediation, except with alcohol! After quitting his position at Yahoo, he cashed in a bunch of stock options and started up Delicious Brands. He also convinced a few techie friends, like Jonathan Abrams of Friendster and Socialzr fame and Saar Gur of Charles River Ventures, to invest or advise.

Who would you have seen if you squeezed onto the packed invite list and made it out to Supperclub on Harrison Street? The uberconnected Auren Hoffman, pictured above, arrived in crutches, the result of a nasty soccer injury. He got plenty of sympathy. Yelp's pretty-boy founder Jeremy Stoppelman and his model brother Michael showed up. The newly 30 and effortlessly charming Jared Kopf came out with his team at yet-to-launch Adroll, his stealth advertising startup. Other people spotted in the crowd: venture capitalist Eve Phillips from Greylock Partners, OpenDNS founder David Ulevitch, Foundation Capital VC Mike Brown, Robert Pazornik from LicketyShip, and Jeff Hammerbacher, Facebook's guy in charge of data.

Supperclub is rarely, if ever, the scene of a dotcom party. There's a large circular bar by the entrance, making the room crowded, stuffy, and difficult to maneuver around. And it's loud, too. Lotus hired DJ Solomon to spin tunes and keep the crowd moving all night, making it all but impossible to hear in sections of the bar. Not exactly the best setting to give an elevator pitch, but perfect for learning if your VC is someone who knows how to get down.
