I've signed up for a social media course.
It is entirely online and applied. I can apply it as I go along. It uses a combination of short pieces to camera (a minute or so) with text, webinars and written assignments.
It's taken me 13 months to commit having been impressed with a presentation at Learning Technologies 2011 (see this blog, February 2011), seen the team at a stand at Training Technologies last week and then doing a 7 point taster yesterday.
