Dick Moore (sometime collaborator, friend, and Trustee of ALT) writes a practical and insight-rich "how to" about making short instructional videos on his Tools and Taxonomy blog. It is just this kind of useful material that gets lost (i.e. is not written) when people with knowhow to share take the easy way out and write performative snippets rather than thought-through pieces. (I am as guilty as the next person in this respect.)
Whether next year's new year resolution will be easy to live up to is another question.
