The "Ask Sage" questions and answers forum is powered by a free open-source engine, askbot. It is hosted at sagemath.org and backed up. This way, the Sage community owns the data of questions and answers at ask-sage, in a documented format. If the development of askbot were to stop, the Sage community would still have a way to extract the data and transfer it to another free open-source Q&A engine.
By contrast, with a questions-and-answers forum at Stack Exchange, the data would be hosted at Stack Exchange, could not be backed up by the Sage community, and if Stack Exchange decides to turn off their website, or goes bankrupt, all is lost.
I don't think it makes sense to have two Q&A sites for Sage. Stack Exchange does offer some advantages in terms of stability, but these come with a price (as @slelievre has pointed out). ask.sagemath.org already appears at the top of google searches for Sage questions, so I'm not sure moving to SE would appreciably increase visibility of Sage.
