Are you asking about email or messenger or search engine? (BTW, who is that in your avatar image? It seems to be a telugu actress )

I used an MSN tool for my niche/keyword research. On how the keyword is search based on commercial intent of the people doing it. Really helpful for me.

I'm talking about both e-mail and messenger.

Erm...MSN is prettyyyy big. What do you think in terms of? Bing? Bing is gaining sick marketshare as we speak. Microsoft is doing some behind the scenes shizzle with that search engine in co-op with Yahoo! Both of them are playing dirty tricks in order to get right up behind google - you'll see soon

MSN now rocking with lot's amazing features, have you checked latest Bing silverlight version Webmaster dashboard features ? it's really amazing

msn=Microsoft.. Microsoft jumped on the search engine ladder a lot later then google etc and regret it profit wise this is why you see loads of ads on tv for live/ bing etc they are trying to get up with google and are making it slightly.. but only because its Microsoft! :P

MSN is famous but not as a search engine, because a very low percentage of people are here to search in it,,

I agree to you i think it has taken long time but, still at the same positions with same features. They have to bring some fabulous changes for betterment of that.

man is famous for hotmail mail service not as search engine..
but google is the best one.
