Remember those rather amusing double toilets in Sochi? (O.K., I have no class. I admit it.)
They made me (and millions of other people) laugh, because, well, it would be kinda awkward... one per is quite enough for me.
I kind of feel a somewhat similar awkwardness when I see (not a rare event) two answers by the same user to a single question on the main site here. While I can see this as perfectly acceptable on meta (or math, or somewhere where there might be two unique and equally acceptable answers), my sense of awkwardness makes me wonder if I'm being a killjoy.
This comment finally nudged me to ask this question.
I would split that into two answers so the two suggestions and be up- and down-voted separately
So I looked it up at Meta.SE.
Mostly - but this may be a confirmation bias revealing itself - it seems people feel that
[i]n general there should be one answer per person per question; if you need to amplify your answer, edit it! - Jeff Atwood (Oct 8 '09)
When there are multiple possible answers, I crowd them impolitely into one answer box. What should the etiquette be on the main site here?
I promised you a second question, and in keeping with my lack of class, here it is: Which seat has been left in the proper position? Bonus points if answered correctly!
