Recently, two 3D printing professionals posted the following AMA to r/IAmA:
The AMA got a huge respond, reaching the top of r/IAmA with a score of 1900+ and over 1000 comments. The AMA was unique because they promised to design and create 3D printed prototypes of the top three upvoted ideas.
The three most upvoted ideas were a functional mini desktop catapult to fling things at coworkers, Beyonce, and a “half-triceritops, half-ostrich figurine wearing a tie, checking its watch and carrying a briefcase”. So basically one legitimate idea and two ideas that were upvoted because other redditors thought they were funny.
Additionally, after the voting officially ended, a ridiculously difficult idea was upvoted to the top of the comments. In an edit to the AMA, they explained that they would actually give this idea a shot even though they might not create a fully functional prototype.
I am always excited to see these types of AMA’s and interactions happening on reddit. There is clearly a trend as more and more leaders realize that crowdsourcing ideas and information on reddit is viable.
In regards to the 3D printing AMA, they might have had a better response if they posted the AMA to r/3dprinting or one of the other 3D printing communities. They would not have received as many eyeballs in a niche subreddit, but they would have received better ideas and higher quality interaction with 3D printing fans.
