Just a thought... I stuggle at times reading through a hand example in an article or quiz and really following the action, as it in a different format than we experience in the heat of action.
A cool idea would be to have a link to the hand replayer so that you have the option for examples pop up in a new window. That way you can review the action via the written example, and experience the action as it would occur live. I'm sure this would assist in the learning process, as I for one tend to recall a hand I've played much more readily than something I've read.
To take this one step further (and obviously much more of a project to get it to work) would be to actually have an interactive hand replayer where you play the hand and get feedback from the replayer as to why each play is the correct/incorrect move. Links back to the appropriate text in the articles could then appear so as to reinforce the appropriate or key plays at each step of the action.
One more thing. Make ♠_evil:red (not pink) and apply gold lightening bolts down the sides.
