Are there any studies or data that show sticky navigation elements are effective at producing click through, for example .... http://gawker.com/
I"m thinking about putting one in, but wanted some references before running my own split test.
Fixed navigation works great for webapps, not so much for websites.
I see websites like areas where content is king, where users go to read/watch/hear information. The purpose of a website to be informative and is some cases entertaining. When I read, I hate to have a top navigation which only shows me that I can go back to the homepage, or click a new category to read/see articles or pages from that section.
On the other hand, webapps are application that give me, the user, more functionality. Take gmail for example:.
I really like the fact that I don't have to scroll up in order to delete some messages. That would be a waste of time, and since I already am familiar with the menubar, I have no need for contextual menus or other UI overload to get what I want done fast.
