I wrote about the process Twitter went through when it redesigned its profiles, and asked how much it might matter to the company:
Even for a product known for its long learning curve, Twitter’s old profile pages could be vexing. The text of your biography smushed on top of your header photo, making both hard to look at. Background images tiled awkwardly. And when you looked at a profile, says Sachin Agarwal, a product manager at Twitter, "it was impossible to quickly figure out — who is this person?" Dave Bellona, a designer at Twitter, puts it another way. "It was hard to make the old profile look good."
