I've NEVER had a problem with it. Others have had chronic problems with it. In the final analysis, I think it's like a decoupling cap. Sure, your circuit might work on the bench without it, or maybe even in the field without, and maybe 100% of the time, but saving $.03 for one resistor isn't worth the trouble that NOT having it in could cause. Put the resistor in and be grateful you never had a problem with it and learned the easy way.
