It has been more or less accepted that
big-list questions can be useful and are welcome in the site. But I think we should try to define some guidelines on how these questions should be handled by the community.
I can see basically two kinds of approaches:
One item per answer (example: What packages do people load by default in LaTeX?)
One answer with all items (example: What are other good resources on-line for information about TeX, LaTeX and friends?)
So, the questions, ¿Should we try to prefer one style over the other? And, if so, ¿which one?
In any case, I think any such question has to be made Community Wiki. First there is no “right” answer,
big-list means many answers are expected. Moreover, the answers are likely to change over time (new packages coming making some old obsolete, new online resources showing up some going out). And I say this because the later example is not, yet, CW. (Does anyone has the power to do this yet? Or do we still need a moderator?)
Now, the advantage of “one item per answer” seems that we can discuss and vote answers individually. Which I think has been proven quite useful in the first example, so most common (useful?) answers naturally flow to the top. And it's easy to "amend" new or additional information to each answer as comments.
I also see the appeal of “one answer with all items”, it's all just right there, much less clutter, can be organized much more nicely. For example in the question about on-line resources, Stefan Kottwitz split his answers by Newsgroups, Webforums, FAQS, ... Which is impossible to do with the alternative approach.
Anyway, I think the “one answer with all items” has its problems. First, and that's why it should be CW, for ‘the’ answer there should be no editing etiquette, the only way to add new information is to edit said answer. For example, the answer for the online-resources doesn't mention resources in spanish, if the answer were to be made complete I should be able to add them.
But the problem is then that there is no way to “moderate” (as a community) the answers or the edits made to the “big-answer”. How can we know, from all the individual items, which ones are popular? which ones are more useful? But even worst, what happens if we all go an add all the links for all the (La)TeX online resources out there (the big and the small) in all the languages spoken in the world? Wouldn't just the answer become an useless bloat?
