I have the same issues! I used to keep draft ideas in a Wordpress account, but had over a thousand that never got worked on :)
It is a good habit though, but looking back at some of them it is clear, I need to take better and more meaningful notes, as often I have no idea what the post was going to be about .
Yes! Often, though, I'll remember what the post was supposed to be about but whatever quality made it interesting to me at the time has faded. Sometimes I'll write it anyway, but usually it ends up being a hard slog, though occasionally the act of writing revives my interest in the topic.
