There are quite a few list type questions that are present in the site. Are these type of questions alright and/or encouraged ?

From Oli: I'm marking this as featured.

I would like to have a proper discussion about the future of list questions. If you have a view on the subject, please share it below and we'll slowly chisel out a framework for supporting them, or if it turns out they're always going to be filth, we can issue (and more importantly, practise) an outright ban.
