Usability of that announcement homepage is simply horrible.
unless this is on purpose (to lower the amount of users somehow to let the system avoid a spike or something) then I really don't get it.
and after you go in, it's a pinterest wall.
The feed's popups are too high for a 600px screen. And since it is javascript, you cannot scroll up and down the whole window frame. You cannot open items in tabs using ctrl, javascript will capture the mouseclick, you have to rightclick and choose from the menu. Did I mention how much I love javascript and its improvements to user experience?
