In the spirit of being bold, I created a tag parallelling TeX.se's big-list
, where there are 85 questions tagged that way, some with over 100K views.
The clone I created on Emacs.SE is here: big-list, although I would suggest to peruse the TeX.SE version which is more developed and will show the kind of questions that are suitable for this tag, as well as some that were posted with that tag and then closed.
See also:
one related question and some preliminary discussion here on meta: Big list question on writing mail with emacs and the corresponding question on the main site: Reading and writing email with emacs.
"This question is intended to provide a canonical landing point for users wanting to deal with email using emacs. Please post only one package/solution per answer, with as much details as you can."
Another test case on the main site (placed "on hold" shortly after I asked it, but the big-list tag was removed by a moderator before the question was placed on hold, so I used a stylized title to show the "big list" designation): https://emacs.stackexchange.com/questions/13197/big-list-what-do-you-use-org-mode-for
An earlier question with a similar flavor that received a relatively high number of upvotes: What are all the ways of launching a shell from inside emacs and what are their various properties?
In making the case for, one thing I would point out is that Area 51 asks for our "answer ratio" to be above 2.5, and it is currently (as of June 16, 2015) only 1.7. This suggests that however we go about it, we should find ways to create multiple answers to more questions. This goal will be more challenging to reach if every question is constrained to have one definitive "right answer".
To give fair play to the case against, I note this recent exchange in chat:
"So, I wrote What are all the prepackaged Emacs configurations and what are their advantages [dead link] and apparently it's "opinion-based". I basically wanted to ask "Hey, what's the point of using one of those". Many similar questions are very valuable on stackoverflow, so why can't we have them on emacs.se?"
"Many similar questions fall through the cracks on SO, because there aren't enough people voting to close. That doesn't mean that they're useful questions. These list questions always end up being badly curated, grossly incomplete, and generally useless."
tl;dr I do think the case of TeX.SE shows that such questions can play a valuable place on some StackExchange sites -- what about Emacs.SE?
