Social networks first page
There´s social networks for everything: baby boomers, wine lovers, music, books, photographers, personal tastes and a lot more. But, independent of the subject, they all have in commom the layout of its first page: content and advertisement.
This happens because all of them needs to explains what´s the network about, attracts people and show all the content that is added all the time in the network. And all of them need to do that in a attractive, brief way and at the first page.
Some sites below are famour others don´t, but I believe it´s important to show them so it´s possible to study their caracteristics in commom, in the content and in the layout.
