You’re not the only person to share that sentiment. I post a lot. Few reasons.

1. To try and help build Lemmy. Need to have an influx of new material consistently or things get stale and drop off.
2. To make other people sick of me so they start posting themselves which just goes back to point 1.
3. Because I am suicidally depressed and the constant posting/reacting to notifications distracts me from my own problems long enough that I get to breathe without hating the fact that I am.
4. I have been stockpiling stuff for years for seemingly no reason. By posting, I can justify my past memegoblin behavior.
5. It’s fun
