Facebook bug lets you see how many people viewed your post

What if you could see exactly how many people saw your post on Facebook, and compare that to other users posts?
The bug was reported by several users on Twitter on Wednesday, who started noticing view counts next to their posts.
Normally, "reach" - a stat similar but not identical to the view count is only visible by page owners for their own posts; individual users should not be able to see any kind of statistics beyond the number of likes and shares, even for their own posts.
If you can see the view counts, enjoy it while it lasts, because Facebook has no plans of enabling this "feature" for all users - it's there for Facebook's internal use.
