Well I think using Mastodon is a failure for me.
I used it for 2 months as a way to share some interesting things or thoughts, and discover the same from others.
It appears though things which are interesting are not frequent, and when they are, deserve more than 500 characters associated with them.
In the end, Mastodon truly is microblogging, but the utility of microblogging seems very niche, and not for me.
Back to the drawing board.
