You have to give it to MSN. They are definitely pushing forward into the space and looking to design the best possible search results.
Unfortunately what I have not seen in the survey is do you want SPAM.
I think they are going to have a huge impact on the PPC space once they roll out of beta, but the results have a long way to go if they plan to be thought of as better than or even equal to Google.
It's funny how the success of Google has recently seen them being referred to with Microsoft like distain. I guess the backlash of popularity is the scorn of outsiders who have difficulty with anyone dominating an area.
