Here’s a video I did while attending YouTube Live on Saturday–well, live–at the Herbst Pavilion at the Fort Mason Center, right on the San Francisco Bay.

The last time I had attended a big tech industry event here, it was the launch of Windows 97 from Microsoft (MSFT)–which was quite a different scene than this entertaining but freaky show, in which online celebrities jumped a little shakily into the analog world.

Let me just say, online celebrities make real-world ones seem 1,000 percent more interesting. But there is also a homespun sweetness to them too and a look-at-me striving that can be downright heartbreaking.

YouTube Live was the online video giant’s “first ever official live community celebration” and also its first try at a live-streamed event. The YouTube Live broadcast online drew about 700,000 viewers at its peak.

As such, as Peter Kafka of MediaMemo notes: “That is almost certainly a record for a Web-only event. But it’s a nonevent by mainstream entertainment standards.”

I am not sure big ratings were the point, though. Nonetheless, the show did attract a passel of Internet stars, including YouTube Founder Chad Hurley, who sat with Google Co-Founders Larry Page and Sergey Brin right up front. Google (GOOG) owns YouTube.

Here is a video of the event, including an interview I did with Obama Girl, as well as Hurley, and also some snippets of the professional performers (Katy Perry, Will.I.Am and Akon) and a passel of online celebs (including the “Free Hugs” and “Will It Blend” guys) appearing onstage:

This weekend, YouTube is going analog, showing off a bunch of the freaky people who have become online phenoms, at YouTube Live, its “first ever official live community celebration.”

Taking place in San Francisco on Saturday, BoomTown and thousands more are going.

And, frankly, I am not sure I want to meet some of these folks, including the truly warped Fred Figglehorn (the No. 1 most subscribed channel in YouTube history), Obama Girl and Brandon Hardesty, the guy who does movie reenactments.

Also attending the event by YouTube, which is owned by Google (GOOG), are some actual stars, such as singers Akon and Will.I.Am.

YouTube says there will be more than 50 YouTube and real-world stars scheduled to appear, with a combined 2.5 billion video views on YouTube.

Will I be bringing my video camera? In the words of a more recent YouTube phenom, Governor Sarah Palin: You betcha!

Here are some YouTube phenoms:

Obama Girl

Fred Figglehorn

Brandon Hardesty

Will.I.Am
