The search engines seem to be becoming more and more similar these days. In the good old days they all had their own idiosyncrasies - which made it so much easier to tell them apart. Google ads' titles had 25 characters while Overture allowed you 90. Now Yahoo wants to mimic Google and MSN is changing to make the differences seem smaller.
Even LookSmart is calling their interface the AdCenter just like their former search partner MSN.
Uniformity I know makes things easier for analytics and using the same ads on different platforms, but the branded differences were okay by me.
I just came back from Shop.Org and the big three were there - funnily Yahoo and MSN were pushing there search products while Google was all about Checkout. In previous events Yahoo would have been promoting their shopping cart and MSN the quality of their content areas, while Google would have been the sole search pusher.
Even the handouts from MSN and Yahoo! were the same - mints.
MSN you lost the mint round!
