This question is related to the post Please correct the tool tip message on edit link in Stack Overflow. 
When I click on the edit link on a post, this is what I see on Stack Overflow, Meta Stack Overvflow and English Stack Exchange.
Stack Overflow does not show the revision drop down but Meta and English Stack Exchange does.
As the title says, why there is inconsistency on edit functionality between Stack Exchange sites?

A:

The inconsistency comes from whether or not you have normal editing privileges on the site. When you don't, the edit link is missing the .edit-post class, which causes the inline editing code not to be hooked up. I'm not sure whether or not that's intentional.
