Not an accurate assessment unless you make it from the time of promotion to master, going forward.
Yeah... all those 'free' skins are supposed to be in the nature of shared community uploads from hobbyists learning the skinning craft and expanding their creativity and having fun with the community.... sadly, making it to master these days, isn't necessarily seen as becoming a responsible elder of the community with impeccable behaviour and community spirit... it seems all about the $$... I know it's been very handy for masters to be able to sell their work and we have benefited from some superb skinning from our masters over the years and I have many of their skins.. but when the almighty dollar becomes the main motivation from the skinner, and/or stardock, to reach master ... it really lessens the overall status... and cheapens the tradition...
first masterskins priced at $20 says it all.... skinner's prerogative? yes... judgement? dubious...
especially after Stardock generously altered the % arrangements to benefit skinners recently...
John is designing audio software interfaces now for several companies around the world and getting paid for it (but not nearly enough for his high quality of work IMO).
see some here Psychosis81.... link... have a scroll through... and here... link... 
and no... you could never pay v by the hour for his work.... he is too much the perfectionist.... each pixel has to be...perfection... and tried a zillion different ways...
but that being said, the audio companies are getting a good deal for the quality they are being provided with... it knocks their socks off, the creativity and quality...
yea, i had a feeling he quit...... he was definetly my favorite skinner.. i think i have bought every skin he ever made lol.. sucks sucks sucks
never say never...
if/when he ever has some downtime... I'll keep prodding for another, I assure you...
but it has been fabulous to have his skins updated to continue using... they'll never date.... classics...
