Thin White Lines - Illustrator to PDF
Hello all,
Ok - we all know what this questions is about - why is it than when I save an Illustrator file as a reduced size PDF, thin white lines block around text content, and sometimes in images.
For example:

Zooming in / out, moving, the line stays the same thickness, and comes in and out.
In my 10 years working in Illustrator / Acrobat, I have struggled with this problem.
Yes, I know they are artifacts; yes, I know turning off "Smooth Line" or whatever will sometimes fix it ON MY MACHINE; yes, I understand that this often has to do with flattening transparency (which is unfortunately critical to reducing file size to an acceptable level for e-mail / web sharing).
Can someone, preferably an Adobe employee, explain once and for all either:
A) A reliable way to avoid this when exporting AI to a small, easily shareable, digital PDF.
OR
B) Tell us all when this will be fixed.
I'm tired of people saying: "Well, it won't show up in print" - this is for a digital file!
I find it unbelievable that we have had to struggle with this for so long - stop making useless features, and fix what actually wastes all of our time please.
