In the past, when I've edited an article on EZA, it has gone offline for several days until it is reviewed. As a result, sometimes it also disappears from the SERPs. Today I edited an article (nothing like finding a spelling error in the first sentence of a article that has been live for months) and resubmitted. Within 30 minutes, I had a notice that the article had been reapproved.

The slow turnaround time as made me reluctant to make edits in the past. Hopefully this is a trend for the better.
