In testing my Greasemonkey script for counting votes for a tag (to address this question), I noticed a discrepancy in the results.
The wording for the tag badges is:
As you use Stack Overflow to ask and answer questions, you'll earn badges, which appear on your user page and in your user card.
Tag-based badges are awarded for participating in non community-wiki questions with particular tags. If enough upvotes are earned in a tag with 100+ total questions, the badge will be automatically created and awarded.
This wording implies (to me at least) that votes for both questions and answers count towards the total for a tag-badge. However when checking my script's results I noticed that the total count for maven-2 as measured by the script comes to 259, whereas the count on the stats page is 250. I have 9 votes from 2 questions on maven-2, so it appears that only answers actually count towards the total (note I've excluded community wiki results from the search, see example query below).
Here is the search I've used as the basis for my count:
Can either the wording on the page be changed to clarify that only answers count, or the processing changed to include question votes?
