Twitter CTO leaves company

Twitter seems to be having a big shakeup this year, what with the layoffs and shutting down Vine [0]. I wonder if this is part of it. I hope it shows that Twitter is becoming more serious. They've done very little meaningful innovation in the consumer facing product in years, but the product remains incredibly addictive. I spend 1-2 hours a day on it (unfortunately).

Twitter's an incredible service, I hope the execs can turn it into a great company.
