Ever since Google started being _really_ fast with index updates, all the others have been trying to catch up. By "really fast" I mean my work launched a new campaign on Sunday morning and it was in Google's results by Monday afternoon. > Is there any good reason why I shouldn't block (or at least > significantly slow down) MSNbot, MJ12BOT, and Yahoo > Slurp! ???

Depends how much you care about Yahoo's or MSN's referrals. In the consumer space I work in, Google still accounts for the vast majority of hits (>85%) and a similar proportion of sales. MSN + Live are around 10%, essentially through Microsoft's domination of people who don't know how to change their home page let alone install an alternative browser. Yahoo gets around 4%. For us, these are the people we target so it's very important. For you, it might be less important.
