Is there any option to change design on stackexchange sites?
Current school notebook-like theme is not good.
I just want to echo what waiwai993 said and add a little something:
If you don't like the current beta theme, you are free to propose an alternative style to be used when the site goes out of beta on the site's Meta. Jeff has stated something, somewhere, about Jin Yang designing the site's style, but I'm sure if the site's community knows what it wants and one of them can supply it, then there will be no hesitation to adopt it.
