I just checked my website with all the major search engines and so far MSN Live is has impressed me the way they index. It has indexed all my new posts and pages (even the ones I just posted today). I reupdated google sitemap, it didn't do a thing. Yahoo is still way behind. I am starting to like MSN Live now.
Not sure if many people use MSN Live as much as Google & Yahoo!. To be honest, I don't use MSN Live, I mainly use Google & Yahoo!, but we'll see if MSN Live can recover from their search result disaster.
