I thought this was a pretty interesting article, until I went to bing.com and tried a search. The interface is not "super clean". In fact, it looks just like Google's (with all the silly previews and panels on the left/right) and as soon as my search results came up it asked me if I wanted to integrate my results with my Facebook friends or something... they're just copying all of Google's new crappy features....
Ill try bing for a bit, though the first search gave me a glimpse and it was not much different... classic add on top of search results. And it still looks like google a bit, but who can't look like google? If you don't look a bit like google you are too different and you are doomed right away.
The fact that search engines can be swapped on a whim nullifies antitrust concerns, and as for the features in question they can be toggled over and even turned off completely if you don't find value in them, thus I fail to understand the brouhaha involving this feature and certain bloggers pretending to be lawyers.
