StumbleUpon gets kudos today for being the first social media site I have seen to dress itself up for Halloween.
If you head over to the site you will notice the entire site has turned from its standard bright white and blue theme, to a hard black and gray theme with orange links and a festive little StumbleUpon logo.
So outside of a black color scheme and some orange fonts, there is nothing really mind blowing about the costume but we appreciate StumbleUpon actually making the effort.
