Well, more than a month has passed, but here we are. My first thought was to pick out the Best of the Best from the 151 stories that made my original list, but that seemed like a fool's errand for various reasons. Below you will find 15 categories, subgenres if you will, and in each I have listed five stories that made my best of lists in the last decade. They aren't the Best of the Best, just excellent examples of their subgenre. Of course, some of these could have easily fit into several categories.
And by the way, there is a hidden category tucked away here: stories with twist endings. There are many examples below but to point them out would be counterproductive.
As a lagniappe I have added a Classic story in each category. "Classic" here is defined as a great story that was published before I started reviewing.
Availability! In each case I have listed the original publication unless I thought there was a more available site. I provided links to a few stories that are available for free on the web. You may find others elsewhere on the web but I suspected those sites might be copyright-violators or malicious, so I skipped 'em.
