At Zappos, careers live by the Twitter, die by the TwitterSNo company has embraced Twitter quite like Zappos, the online shoes-and-whatever-else retailer — from its CEO, Tony Hsieh, on down. It even hosts a live feed of all Zappos-related messages on the microblogging service. That has made it easy to gather that the company is going through a tumultuous round of layoffs.Zappos_Jackie reports that she was laid off an hour ago; other ex-employees are proclaiming their lasting love for Zappos. We look forward to the New York Times updating its trend story about how companies blog about layoffs. They must now Twitter them instead, lest misinformation spread quicker than sluggish RSS feeds. (Oddly, Hsieh never mentioned the pending layoffs in an interview he gave to the Times about Zappos' vaunted corporate culture.)
