I assume you meant the tab NEXT to Businesses?
OK, I must be particularly dense. I don't see a "businesses" tab. I don't see ANYTHING that says "businesses".
Oh, alright, I AM dense. Silly me. I have to first click on "Local", then do a search. Unlike Google, live.com doesn't offer-up the option of a map when just searching on a city name with the regular search.
I think they have taken interface minimalism to an unreasonable extreme. They've out-Googled Google to the point of lack of usability.
Oh, and not that I care, but what happened to the REST of the live.com features? The ones that were there before this new search? Do you have to log-in first? How would a new user ever know that there is anything but a search engine there?
p.s. Receptional, we posted at the same time. Here's the REAL BREAKTHROUGH - Microsoft has perfected an over-40 filter! Nobody over 40 can make heads or tails of the UI! ;)
