I'm seeing something really strange when I look for my site on Yahoo.... when I search using the keywords "drew barrymore" my site is often listed as #2, but every once in a while when I refresh, it will appear as #1. When I refresh again, it jumps back to #2. Does this mean it's in the process of changing? It's always been at #2 on Yahoo, so it would be nice if it was moving up.

I'm not sure how Yahoo works as far as updates...
