Why is IO9 shouting at me?

It's like I bought the large print version of the site and now I can only see 3 articles per screen and no index of new articles.. my poor mouse wheel is knackered. It's like having a magazine for nearsighted people on the internet.. except you can't adjust the text size to make it readable if your not nearsighted.

Better still.. where can i even discuss this? Here? I have no idea what this does so i'll type and post it and see what happens.
