Friday we reported on a Back Link Update, and as suspected, it was not a major change that affected search results. Since then, WebmasterWorld has named the update, Pluto (kinda cute, don't you think?). Which reminds me, doesn't Ask.com have to update their Smart Answer for said (message # 3061576),
I agree this one isn't anything to write home about. Like Pluto, I think this would be a shrinking update; the SERPs aren't really changing. :)
Continues forum discussion at WebmasterWorld.
