Twitter (TWTR) CEO Jack Dorsey seems to make hires for both Twitter and Square (SQ) based on executives that don't currently use Twitter. Maybe this reduces the chances the person has some unsavory tweets in their history or maybe this is his way to grow the user base. The new Square CFO just joined Twitter back in November and made her first tweet on January 2. Ironically, the tweet was made only a couple of days before her announced hiring at Square. https://twitter.com/AmritaAhuja/status/1080665580229648386!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");Twitter remains a buy under $30 as it adds one influential user at a time.
