According to our Robotics FAQ
[...] our meta-discussion site hosts a section of constantly evolving frequently asked questions that document everything about the site
Unfortunately, so far there are no meta questions tagged faq. So, is it too early yet for us to consider any questions frequent, or should we randomly tag some existing questions, or should we vote on which questions merit the faq tag?
Nah, we don't need it yet. Most sites don't need the faq unless they have some large policies/how-tos. We shall probably be able to fit most of our policies in /faq.
For example, see the tag on meta.chem. We've got one post of site promo, one post for a homework policy, one for a TeX tutorial, and one guide for closevoting. Currently, all we have is this promo post on Robotics. We could make the closevoting guide. The HW policy post makes no sense to be here, and we probably don't need the TeX guide (we have MathJax enabled, but we may not be using it as much).
On the other hand, RaspberryPi.SE has an empty faq tag.
On the Internet, FAQ has come to mean much more than Frequently Asked Questions. It means "hey, newbie, read this!".
If there are any policies we keep needing to link to, then it may be a good idea to use the faq tag. For now, I'd say we're good :)
Most of the faq pages can be found on the mother meta.
At the moment, we only have the community moderation team to help moderate Robotics, but we are currently looking for moderators pro tempore of our own.
Once protem moderators have been recruited, it should be easier for us to manage which meta questions need tagging with moderator only tags like faq and featured. Since Manishearth mentioned it I have already added a How can I format mathematical expressions here, using MathJax? question and given it the faq-proposed tag to suggest that this might be worthy of a faq tag.
