<p>Here <a href="http://data.stackexchange.com/stats/query/82928/tags-with-no-wiki" rel="nofollow">is a query</a> that produces tags with no wiki from the Stack Exchange data dump. These are sorted descendingly by the number of questions that have that tag, hence tags that need wiki's and are used the most. I include the length as a potential indicator that a wiki, even if it has some text, can be potentially expanded upon.</p>

<p>Unfortunately the data dump can not keep up with your recent work! But hopefully this is useful enough to see potential candidates.</p>

<p>Note that a tag wiki and a tag wiki excerpt are different, and you can have wiki excerpt without a full tag wiki (it appears all tags with wiki's have an excerpt, I assume this is by design). Included in the query are the tag wiki excerpts, so you can filter them out as well. I include length so one can also see short wiki's that are potentially candidates to be expanded upon.</p>
