I was in the middle of writing this list and read an article about Lake Superior State University releasing a similar one. In any case, here's mine. Take no offense if you use these phrases, as I have been guilty of using them myself.
In 2011, I hope to never again hear or say:
Going forward - "from now on" or "In the future" will suffice
Reach out to - just say "call" "email" etc. and stop trying to pretend you have an intimate relationship with someone in the Purchasing Dept.
Granular - "detailed" will do
Having said that - whatever happened to "on the other hand"? Better yet, why not just take a stand in the first place?
Just sayin' - so do you mean or not mean what you "just said"?
Finally, let's avoid a technique a handful of writers are good at but most of us are not. I hope to never again read or write a status update or tweet where one states a well known phrase, restates it, inverting the subject and direct object, and then, in Emperor's-New-Clothes-like fashion, receives scores of "Likes" or comments claiming it is philosophically or theologically profound, e.g. "The question is not 'Do we believe in God?', but 'Does God believe in us?' or "Let's stop singing our songs and let our songs sing us".
What's next? "It's time to stop mowing our lawns and let our lawns mow us?"
Hopefully, I will avoid using these phrases in 2011. Going forward, I'll be reaching out to you, so let's celebrate the New Year! Having said that, let the New Year celebrate us!
...at the granular level.
Any you would like to add?
