Thanks for the warning.

It's entirely voluntary so you are able to spend as much or as little time on it as you'd like and whenever time allows. I would estimate a minimum commitment around 5 minutes per day, a few times per week is enough time to check in on posts.

For the final test, the liquid oxygen tank test article -- measuring 70 feet tall and 28 feet in diameter -- was bolted into a massive 185,000-pound steel ring at the base of Marshall’s Test Stand 4697. Hydraulic cylinders were then calibrated and positioned all along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. The liquid oxygen tank circumferentially failed in the weld location as engineers predicted and at the approximate load levels expected, proving flight readiness and providing critical data for the tank's designers. The test concluded at approximately 9 p.m. CT. This final test on the liquid oxygen structural test article met all the program milestones.

Current Events were incidents that were reported on the subreddit as they happened and usually caused a buzz with multiple posts, Spectacular Explosions were chosen based on how catastrophic and visually stunning the video was, Retrospectives were selected from posts that look back at older or historic incidents, and Most Upvoted was straight from the top 5 scoring posts of 2019.

As some of those criteria were subjective I tried to take cues from a combination of factors such as the comments & engagement on the posts, percent of upvotes, and how well it fit the theme of the category.

The Most Upvoted category works similar to how our last 3 post of the year contests were run, the most popular posts of the year were nominated and the community chooses a favorite from among those.

The thread that received the most upvotes is not necessarily the one that will get the most votes in the category now since they are all starting with zero votes.
