As far as the phrase "pre-planning" (planning something before you plan it) goes, it's as ridiculous and rhetorical as two of my other pet peeves, "pre-heat" (heating and oven before you heat the oven) and "pre-authorization" (authorizing something before it's authorized). Whether you plan something before it's considered necessary, it's still planning. If was in 5th grade and planning to go to college, am I actually pre-planning to go to college because I don't have to plan to go until I get into high school?
Obviously another Americanization of a perfectly good "pre-existing" (something that exists before it exists, like a pre-existing condition) word.
We LOVE to complicate things, don't we? LOL

This one has become one of my major pet peeves, as of late. "Based out of" is simply an Americanization of an existing term. We Americans love to change expressions around; it seems to be in our genetic structure, or something. It is definitely grammatically incorrect.
The main justification for its usage seems to be, "...if someone works mostly outside of a location that is his or her base, then he or she is 'based out of' that location".
Tonight I ran across a Wikipedia article about a radio station with the call letters WAYO. The entire article consists of one sentence:
"'WAYO'-FM is a radio station based out of Rochester, New York, broadcasting at 104.3 MHz on the FM band."
There are many people out there with greater knowledge of English than me, but I spent 32 years in broadcasting and I can safely say that there are few, if any people that know more about it than I do, and I can guarantee that it's impossible for a radio station to operate outside of its location for ANY length of time. Obviously it can broadcast beyond city limits, but it can only do that from within the station.
Therefore, the argument I mentioned that attempts to justify the use of the term "based out of" holds no water as far as I'm concerned. It's simply trying to justify the growing misuse of the term "based in".
