As you may know, we have a blog. As part of writing for that blog, I'm writing an Editor's Picks series - essentially a round-up of some of the great stuff we get on this site.
To do that, I need to find some great stuff to write about. Now, while I could do that on my own, it'd be far more effective to ask everyone to nominate something.
So that's why I'm here. For each Editor's Picks post I do (about every month, give or take a week or so), I'll post here on meta, asking for submissions for inclusion. Occasionally, there might be some special criterion (such as questions or answers in one particular tag).
For February 2016, I'm looking for some of the best stuff you've found on Worldbuilding to write about. To nominate a post, please drop an answer on this question linking to the post and giving a (brief, it doesn't have to be long - I'll flesh it out) summary of what you liked about it. It should have been posted in the month of February 2016.
