I'm a bit worried about this in terms of video.  Video is more tightly linked to audio than the inverse, but good video requires good sound and good lighting.  I think the sound design merge sounds good, but I'm less confident that breaking out Video from the new merge will do anything but kill the Video site further.

It breaks up the community removing audio resources that are key to video and also breaks up the ability to ask more general production related questions that are key to live events.  None of this stuff exists in a vacuum, particularly for live production.  Lighting, video and audio all have to work together and cross over as the cross over questions we have had show.

I think it would be best for video to remain attached to the site and even expand the scope to include lighting unless SSD has some objection to this.  Alternately, a split along the lines of recording vs live might make sense, though I'm still not sure that a split is necessary along those lines either since there is a lot of cross over there as well.  I just notice that SSD appears extremely recording oriented and not very live oriented at all.
