Recently, tags started showing their tag wikis when hovered over. This site has very few tag wikis created, and it would be great if we could get those filled out for our more popular tags.
If you have the 1500 rep and the necessary upvotes for a tag, please consider adding the tag wiki or editing if it already there.
As a little incentive, editing an existing tag will earn you the Tag Editor badge. Furthermore, these edits count towards the Strunk & White and Copy Editor badges.
