“今天，我重返Twitter，作为执行董事长，领导产品业务，感到很兴奋。不错，我同时还会永远担任Square公司的首席执行官。”

    多尔西宣布担任Twitter执行董事长的这条帖子最引人注意的一点是，他并不是去担任首席执行官。该职务现由前Feedburner公司的老板迪克•科斯托罗担任。之前已经有人猜测，多尔西重返Twitter，有可能将科斯托罗排挤到其他位置，尽管从没人真正说明，那会是个什么职位。

    另外，多尔西重申他将继续领导Square公司，也势必平抚了一些风险资本机构的担忧，因为他们已经向这家致力于移动付费业务的初创公司投入了3,700多万美元。这些风险资本机构包括：首轮资本公司（First Round Capital）、Kleiner Perkins、科斯拉风险投资公司（Khosla Ventures）以及红杉资本公司（Sequoia Capital）。

    Twitter也在一份正式声明中表示：

    Tiwtter高兴地宣布，杰克•多尔西已经同意重返Twitter，参与公司日常业务，并领导我们的产品开发部门。同时，杰克将继续担任Square公司的首席执行官。

    伊万•威廉姆斯、比兹•斯通以及杰克这三名Twitter的联合创始人，都做到了慷慨无私，及时站到公司最需要他们的岗位上，帮助公司成长，或者帮助公司的产品发挥最大潜力。从Twitter创建之日起，杰克曾在多个岗位上为之效力。

    作为执行董事长，杰克将与450多人一同工作。这些人由一支经验丰富的高管团队领导。而且，杰克重返公司的时间也恰到好处：眼下Twitter不仅发展速度之快创下历史记录，而且现在我们还拥有全新的基础设施，因此，我们能够始终走在发展前列，不断发布领先的产品，做到更为迅速、简洁而且永不落伍。

    Twitter co-founder Jack Dorsey today confirmed rampant speculation that he is returning to the micro-messaging service. Not surprisingly, he did so via a tweet:

    Today I'm thrilled to get back to work at @Twitter leading product as Executive Chairman. And yes: leading @Square forevermore as CEO. #200%

    The executive chairman post is particularly notable for what it isn't: Chief executive, a role currently held by ex-Feedburner boss Dick Costolo. Some speculation had been that Dorsey would push Costolo into some other position, although it never was really explained what that position would be.

    Also, the reiteration of Dorsey's commitment to Square must soothe some nerves among the VCs who have plugged over $37 million into the mobile payment startup. Those firms include First Round Capital, Kleiner Perkins, Khosla Ventures and Sequoia Capital.

    Twitter said the following in an official statement:

    Twitter is pleased to announce that Jack Dorsey has agreed to return to Twitter in an everyday role to lead our product development. Jack will also continue in his role as CEO at Square.

    Twitter's three co-founders --Ev Williams, Biz Stone and Jack-- have unselfishly played whatever role was most needed at the time to nurture the company and help the product reach its full potential. Jack has been involved with the company from day one in various roles.

    As executive chairman, Jack will dive in to work with more than 450 people, led by an experienced executive team. The timing is fortuitous; not only is Twitter experiencing record growth, but we also now have a new infrastructure that will keep us ahead of that growth and enable us to launch products that will make Twitter more instant, simple and always present.
