Social media is the way of the world these days when it comes to communication. The tweets are allowed by the SEC, free IR/publicity and can come in real time.
PRs will come... as the company has put a lot of them out in the past. Let's see what we get in the next few days or so in the national PR department. I believe we will see something via that platform. I highly doubt the company will put out huge news via Twitter... lol.
Love the updates and communication with shareholders and the market via twitter though.
