Yeah I can't really blame the WoM Client developers as it is free software, but still. You don't go make something, free or otherwise, then just forget about it failing while people are dependent on it.
And all I can say about Notch and Mojang is that I'm glad I bought Alpha when it was cheap and came with guaranteed updates. The way it is going right now I'm not sure if it's worth the money. Notch did promise us an updated Creative Version though... so we'll see how that turns out.
EDIT: Speaking of which, (I feel weird asking for this) maybe you could turn on the Beta SMP server
it would give us something to do while all this craziness is going on.
