Request for Frequently Asked Question Sticky Sorting

[matt grime]

i once posted askign if a frequently asked question sticky could be sorted. i think i'd like to restate that request following bs's two threads

a quick search of "recurring" finds around 7 threads obviously starting with the question 'is 0.9 recurring one?'

the second yet again involved infinity thinking it was a real number.

I think it's a great idea. But there is a lot of material that could be posted on both topics, anybody have any good ideas on how we go about constructing such an FAQ and how we make sure it is clear and thorough?

They've been working on FAQs in physics https://www.physicsforums.com/showthread.php?t=71931&page=1&pp=20
You could probably get some ideas from them. There are also links to their individual threads.
I'd love to help, I just don't think I could contribute much. Maybe we should get a list of questions started. It seems

1. .9 recurring = 1
2. Infinity as a number

are already on the list.
