At our NYC Tweetup in the Hudson Hotel we asked our twittering guests if they have ever tweeted out something that wasn’t entirely true and or have been guilty of drunk twittering.

Let’s see what they have to say.

Last week , Zappos CEO Tony Hsieh sent out a Twitter to all who were in Vegas attending the PubCon Search Marketing Conference and invited them out to magnificant night of drinking, mingling and good rock and roll. The event, which was held at Wasted Space in the Hard Rock Hotel and Casino, became a hotbed of SEO-Meisters who were all alerted about the ‘Tweetup’ via a Tony-Tweet.

Everyone was told that the way to gain entry to the event was to simply write the word ‘Zappos’ on their arm. Below is a video of what went down. Take it away!

Thanks to everyone who came out and partied with Zappos!

As you know, we here at Zappos love the Twitter . And, with our offices being located in Las Vegas, we are in the main vein of almost every conference that is held on the planet. And we were lucky this week to be here for the PubCon Search Marketing Conference, and we held a Tweetup (a gathering sparked by Twitter) at Wasted Space in the Hard Rock Casino that was only announced on Twitter by Zappos CEO Tony Hsieh . We had a blast, and Brett had a very exciting encounter towards the end of the party…..we’ll let the video speak for itself.
