I understand the frustration with speed bumps but for the majority of people (US users at least) the signup nag is dismissible and for the rest of the world, it’s a simple speed bump which helps maintain the operation of the business and provides real value back to the end user.

I also have a Wikipedia account, a Stack Exchange account, a YouTube account, a HN account, and countless one-off forum accounts. This is just the reality of the modern web and per-user customization.
