<p>Twitter co-founder Jack Dorsey is once again stepping back from day-to-day involvement with the company.</p><p>NEW YORK (CNNMoney) -- Jack Dorsey is back to just one full-time job. Twitter's once-exiled co-founder, who returned in mid-2011 to revitalize Twitter's user experience, has stepped down from his operational role at the company.</p><p>Dorsey revealed the news in a post Tuesday on his personal blog, but said the transition has essentially been in effect all year. He cast his earlier return, made at the behest of Twitter CEO Dick Costolo, as a move that was always intended to be temporary.</p><p>"In Spring of 2011, Dick asked me to take an operational role overseeing product, design, and brand," Dorsey wrote. "Our shared goal was to get those organizations back under him as soon as possible, simply because it was the right thing to do for the company. We moved all of my reports back under him in January of this year after leadership was firmly in place."</p><p><a href="http://money.cnn.com/2012/10/09/technology/social/jack-dorsey-square/">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.reuters.com/article/2012/10/09/us-twitter-dorsey-idUSBRE8980XO20121009">Twitter&#039;s Jack Dorsey cuts back on executive chairman role</a> (Reuters)</p><p><a href="http://news.cnet.com/8301-1023_3-57528764-93/jack-dorsey-heres-why-i-really-stepped-back-from-twitter/">Jack Dorsey: Here&#039;s why I really stepped back from Twitter</a> (CNET)</p><p><a href="http://www.webpronews.com/twitter-co-founder-jack-dorsey-is-only-spending-one-day-a-week-at-the-company-2012-10">Twitter Co-Founder Jack Dorsey Is Only Spending One Day A Week At The ...</a> (WebProNews)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dwjdIxP-DyLm9SMLODxR5nteHs8sM&ned=us">69 additional articles.</a></p>
