How many tags lack tag excerpts?

Question

On the main site, we have over 2200 tags, at 36 tags a page and 63 pages. The majority of them have at least a tag excerpt, if not a tag wiki. However, there are a decent number without either. Counting the number of tags without an excerpt manually would be cumbersome. Is there any way to determine how many tags lack excerpts?

Answer 1

SEDE to the rescue! Most common tags with short, long, or missing excerpt or wiki - you can tweak the input parameters as desired.
