Just a simple recommendation (I do not particularly like the abbreviations):
could there be a table on hover, e.g:
* Like the Roomba Forecaster userscript.
The table can contain long details like "Answered the question", "Edited the question", etc.
If the user has <3K, the "Close" link does nothing.
It would be better if the button was disabled for <3K users or led to a dialog explaining that the user needed 3K reputation to cast close and re-open votes.
