I do not know if this is something to do with the coming new year but have noticed that many popular websites have either gone in for a makeover or added some eye candy for users. Popoular ones include Wall Street Journal (website redesign), Gmail (themes for the mailbox), Yahoo ( website redesign, second time in the last one year). The list is big but these are the ones that come to my mind now.
This post is being made from wordpress 2.7 which comes with a completely new layout. I like it.
