First impression is that the site seems to have a whole lot of content all over the place and not that its a bad idea, its just that people would spend more time on the page looking for something which catches their interest. So if you are looking for guide visitors in any specific direction I would consider minimizing the look of the site. Overall it looks great, but I would consider using a logo for the top portion of your site which would add some color because you want visitors to remember the name of the site. SocialNetwork is very general, and thats not a bad thing whatsoever, its just that a lot of social networks now have ridiculous names which help people remember them. So i would encourage you to use a logo to help people to remember.
