Anybody but me think that might be a worthwhile idea?
Yup, being able to skin WC would be a bonus... and being a skinning site it's natural that people would like to be able to decorate it to their own liking. I imagine, though, the important things like site functionality and speed would take priority in a rebuild, and so it should, so it may take a while before we are able to put up wallpaper and curtains... er, windowblinds.
. HTML 5 delivers a full-fledged application platform; "a level playing field where video, sound, images, animations, and full interactivity with your computer are all standardized".
While skinning WC would be nice, HTML5 opens the door to music while we're browsing the galleries and forums... now that would be nice as well, a bit of choogling to help while away the hours many of us spend here. Not only would subscribers/visitors benefit, Stardock could have talking announcements and news items on what's happening in the world of skinning and customisation, etc.... and with embedded video possible also, tutorials can take on a whole new life, not to mention Stardock promotions.
