Should I avoid omitting the preposition after the verb depend in writing? Can native speakers turn blind eye if I drop the preposition? More: depend: Definition, Synonyms from Answers.com P.S.: Please note that you are the only ones who are in charge of providing the authentic knowledge about English language usage. Thus, I have written this to get your consultation. Thank you so much.
As 5jj said, in formal writing, always include the preposition. Native speakers won't bat an eyelid if it's missing in ordinary everyday speech.
Regarding your PS, native speakers can give you authentic opinions on what sounds natural but there are other places to learn about English language usage. Admittedly, some schools, courses and textbooks are better than others but this is certainly not the only authority!
