If you can't get to RootsTech 2014 the keynotes will likely be streamed live. For additional coverage you might want to make a note of the blogs which will be covering Rootstech. It's a high profile blogger group and I'm looking forward to hearing their perspectives, as well as watching some of the live streaming. Some other presentations will likely be available on a delayed basis.
