I tend to read "addicting" as having a slightly more negative connotation than "addictive"; it almost adds...intent?  Anyway.

I have no strong preference. I think "addicting" is technically more correct than "addictive" in the sense that you mean, though. In the same way "healthful" is more correct than "healthy" a lot of times, but still sounds funny. 

Who the fuck says "orientate"?

One of my ongoing goals in life is to be as grammatically pleasing to myself and the earth as possible. I visit dictionary.com and its thesaurus counterpart every day, sometimes dozens of times in a given day. Keeps me fresh.

This is serious pet peeve territory for me too.  How about "irregardless".  I hear that occasionally.  Or "they" in place of "he".  I understand the whole politically-charged "he" as third person, neutral pronoun thing.  But "they" is plural people!  They can use "she" for all I care, but don't mix the singulars and plurals for the love of all that is good and just!

I realize I'm being incorrect by placing the period after the quote, but some rules are just dumb, and meant to be broken.

 

*head explodes*

I remember being taught in an intro journalism class that "he or she" is the technically correct way to go, and some professors expected that, too, so that's how I'll write it in a formal setting.  But I think "they" is colloquially accepted, and like that link suggests, will probably be the "correct" way to do an ambiguous pronoun eventually, and that's how I talk and how I write when I'm going for a broader audience.
