Amazon Echo's official Twitter account made a blunder that may have given hope to followers waiting for new Echo Dot stocks with bated breath. It sent out a tweet introducing an all-new and cheaper Echo Dot, according to Recode, but it deleted the post as quickly as it went out. If the company's social media team didn't tweet on purpose to drum up interest -- post-then-delete is a common tactic used by celebs -- then someone may have fired it out a bit too early. If you'll recall, the tech titan also accidentally posted an iPhone 7 accessories landing page before Apple announced the product on stage.
