How come MSN beta doesnt factor in ALT tags?

My site ranks well in Google but no where to be found in MSN beta

I have noticed that MSN beta does not factor in <img> ALT tag descriptions. I have a site that has thousands of users linking to it with an image which has the keywords in the ALT tag. Google has my site listed in the first page, and this is a term that is incredibly hard to get in the first page of results. Overture recons this exact term gets searched over 100,000 times a month. Now, I wonder why MSN is not factoring in IMG tags, yet Google does.....

This might be one reason google is a little more spammed with anchor text (combined with ALT tags on image links).
