I'm curious as to what style of Q&A that initiative will have to offer. 

I know that unless it has wiki-style editing of questions and answers, that allows its community to improve every post, the impetus for me to try it will not be there. 

http://meta.genealogy.stackexchange.com/questions/1939/why-is-this-site-so-different-from-discussion-forums-a-guide-for-new-users provides the rationale as to why I think our value proposition should not be affected if MyHeritage Q&A turns out to be just another Q&A site featuring long back and forth discussions rather than clear questions and answers.
