I'm currently developing a social network using Rails. It's quite good and it works well, unfortunately something is missing... The design :-( The weakness of many developers (and I'm one of them) is that they lack on arts' inspiration. Look at that menu and the search bar, it's doesen't satisfy me, at all ... The page seems to be too empty especially on the sides. Something is missing but I can't figure out what. Can someone having more estrus than mine, give me some suggestions about the reason of the empty sensation of this page.
The page is available at this url http://i.stack.imgur.com/pVU0E.png
So just how important is white space in an interface design?
