Looks like this morning, Google has unveiled a very impactful match type, modified broad match, in the Adwords platform. I can see this really helping remove some funky matches from clients' broad match adgroups.
Update: we have tested it today already and found that it can be somewhat difficult to make your keyword setups act exactly like you want. Our advice.....start out slow and test before you leap in full force. It could wreck your campaigns if you throw the modifier on all of your broad match adgroups.
