Do you find developer screencasts useful?
martian: Screencasts are helpful for me, but only in a few settings and with one major caveat: There should be little if any transition/fade/time-lapse in the video. A discontinuity of presentation can really make it difficult to follow what is happening.And I agree with many other folks here that a screencast should best be used for an introduction to a subject, and that it can never replace detailed documentation.
