xtramsn is now Yahoo!Xtra.
I see this as a good thing. I like the direction that Yahoo is taking – they’ve done a great job of leaving old-school portal-land behind and are really embracing the new technologies that are emerging. YUI is an example of this.
I’m not sure about the new look and feel of Yahoo!Xtra. It seems to be rather lacklustre and unrefined. I imagine/hope we’ll see some tweaks soon.
