I have edited numerous, probably more than a dozen, FA articles in the past. My experience on FA's is that they are far easier to edit after they have been removed from the Main Page. Once out of the "spotlight", simple edits such as those I normally do aren't scrutinized so closely.  Although, today with Irataba, I must admit I was extra bold—far bolder than I usually get with FAs.  I am usually contented by correcting a typo or two.
