There is probably some merit in the season model that American television takes. "I'm going to release 12/18/24/whatever episodes over the next six/eight/twelve months" is probably more sustainable than a weekly screencast pledge. Gives the author some time off to recharge, and (perhaps more importantly) some time for technology to evolve.

Since I have a background as a poker player one of the coaching sites (deucescracked) followed a season model whereas the others (cardrunners, leggopoker and later bluefire) were more similar to "release videos on a somewhat set schedule but not too strict"

It might actually be worthwhile comparing those sites to subscription based techcasts since both are in the business of selling expert knowledge.

One major difference I see is that the selling point of poker sites is that the players are successful so there might be value in a screencast site that focuses more on "rockstar developers" etc.
