Went onto live.com to see what this is all about. First impression is that I'm not sure what it does. Is it a newsreader? Looks like the "how to render RSS" demos everybody was doing in 2002.
And... doesn't Microsoft have UI testers? I clicked "Add Content", typed "scripting news" in the box, clicked on the first result, got a screen full of XML, hit the back button, and it threw me back to the live.com front page.
Try again... search for scripting news, click "subscribe" on the first item. "Unable to retrieve data, please try again.". Tried again. Ah, now SN appears under "My Web". But all I can see are the current headings. How is this better than bookmarking Scripting News in Internet Explorer?
Update: Joel Spolsky complains about the same problems.
