How often does it attract your attention, when while reading a text (any text) there are some mistakes in articles usage?

Do native speakers themselves make such mistakes? How often?

I'll try to explain why I ask. I'm long since surrendered myself to the fact that proper article usage would forever remain a mystery I'd fail to comprehend.

I've found a solution - reading a lot of texts written by people who speaks good English will improve my understanding.
Speaking of which - the good source would be texts containing 'perfect English' preferably of modern everyday speaking style rich with modern idioms, with extended vocabulary and with some part of direct speech.

What would you recommend me to read, considering the above?
