At this year's Learning Technologies conference, we asked delegates what they thought was missing from the learning-tech industry. Better authoring tools? More interactive video? Dogs as learning stimulants? On this week's show, Ross D, Ross G and Owen discuss a few of the more interesting responses.  If you'd like to share your thoughts on the show, you can find us on Twitter @ross__dickie, @RossGarnerGP and @owenferguson.
