Well, Wedge.org already looks different but that's because I based it off Noisen.com which uses a VERY heavily customized SMF. I customized Wedge.org a bit further, but unfortunately as a result it looks *worse* than Noisen.com (don't ask me why, at the time I thought it looked good enough :P)
I'm still working hard on making Wedge at least viewable by the end of the week. Heck, I could do it now by posting a demo site... But I have yet to determine if (1) it should use the Wedge.org data (users, posts...) and people will understand that it's a demo and the posts will eventually go away, (2) I should make a clean install and no import, and thus expect people to post their test messages on it, (3) it won't be detrimental to our image that our demo site runs Wedge but not our main site, somehow implying that Wedge is not ready for use yet -- which it isn't the case, but I still need to at least implement proper thought privacy and such. (The Friends group is used to posting thoughts for Friends only, meaning I have to ensure per-membergroup privacy is enabled, which can be done easily, but I also have to write the UI for it... Which is a bit more annoying because of my tendency to write complex JavaScript popups.)
