I like the idea of automatically generated FAQ lists. The mouseover text of the faq tab is questions with the most links. That's sounds sensible, links may come for example from duplicates or closely related questions.
So I had a look at the {floats} faq.:
Number 5 of the list: Article appendix with sections and toc entries in the form “Appendix A” is a question which doesn't show any link to it in the right sidebar. The number of 88 views is also pretty low and indicates that this question is not very popular.
Number 6 of the list: Keeping tables/figures close to where they are mentioned shows 19 linked questions in the right sidebar. A result of the many links are its currently 2,612 views.
So, is the sort order for the faq tab correct, or is there a bug? I noticed a strange sort order also with other tags, though I guess this question with 19 links, and 9 duplicates pointing to it, is a good FAQ demonstration example.
Update: Right after I posted this question, that Article appendix question is listed at the top of the faq list:
Still no links shown for this 1st place question, however the question on the 3rd place shows 15 links.
The questions with many links, such as the mentioned frequently linked questions, are indeed very good FAQ candidates, so it would be great if this FAQ feature and the sorting would work.
