Santa Monica-based Tsavo, the online media company which owns Manolith, Twirlit, Kidglue, and Nibbledish, has lost its Vice President of Product and Design, Mike Macadaan. Macadaan is well known in the Los Angeles technology community for creating and running Twiistup, the popular Los Angeles technology networking and startup showcase event. According to Macadaan, this week is his last at Tsavo. Macadaan's departure closely follows the departure of Tsavo founder and CEO Michael Jones, who recently became COO of MySpace. Tsavo develops content-focused web sites which apply technology to serve up more relevant information and advertising depending on who was visiting those web sites. Macadaan said that his team took the site from zero visitors to nearly 3 million visitors per month.
