I have absolutely zero interest in participating in any kind of social media that isn’t an “anonymous forum.” I have no interest in following particular individuals; I’m really only interested in having discussions with random internet users that share common interests. I used PhpBB instances, IRC, and before that BBS systems, and I’m really just looking for the same kind of experience.
So I will never use Mastodon; I think it’s a fantastic alternative to Xitter, but the format just doesn’t interest me in the slightest.
Here’s an idea: Save your photos on your phone or computer. Back them up periodically. Send them over SMS or email to your friends and family if you think they’re worth sharing. Stop relying on social media to give the the dopamine rush that you could be getting by actually doing something useful.
