I manually deleted all of my comments from the past 13 years because I don't trust an app to complete that process. It took a long time, partly because I revisited a few threads along the way. I'm feeling great about my content being unavailable to Reddit, regardless of whether anyone cares or misses it.
Yes, I do miss Reddit. No, I will not go back. Not because I don't find any value in it -- I do -- but because my personal sense of justice gets in the way of wanting to contribute any longer. The time I used to spend scanning Reddit for new information or drama or funny anecdotes is now spent thinking about how I can contribute to my community in other ways.
