If you follow me, I don’t “owe” you a follow.
It’s not an obligation, it’s not a debt, it’s not a transaction.
Read and follow who you want to read and follow. Talk with people you enjoy talking to. They’ll follow back if they feel like it.
Don’t worry if they don’t have time to read your stuff or reply to you. Everyone’s busy and everyone has to decide where to focus their limited attention and time.
Folks, this is supposed to be fun, not a new kind of work.
