As I sit thinking about it, I'll probably not use this tool as-is (or ask others to follow the account) if the bot doesn't send a notification.
That's not actually a complaint. I understand the idea it is just doing a standard toot and that that is what most bots should do.
But as a way to be sure I know about updates to a very intermittent RSS feed like mine, someone would too often miss that a new post had occurred.
