Something I've noticed the last couple/few days is new pages are slower to get indexed and generally when I start seeing that it means they're running something "big" in the background and not increasing the size of the index while it's running.
I really don't know what it is though. It could possibly be a Panda/Penguin run that seems a bit larger than normal and they could be pushing portions of it as they complete, which would explain some people seeing flux and others seeing stability, but the results I've been watching are relatively stable. Some flux, but nothing huge I've seen.
I've also see two seemingly different result sets based on site searches every-other-day for a few days. Indexed page count is +/- about 10% from one to the other.
