A hub is technically an article and not a blog so if you did it in a way that you are informing another person or even inspiring them it would probably work.
Interesting question. I would think that they are since really the only thing that is not allowed is adult material and spam. I'm sure that with your quality of writing this will not be a problem for you.

I don't see a problem with this category of hub, I'm sure you will be able to cut the grade when it comes to publishing a memoir.
Many of my hubs involve memoir. Also other hubs that I have read and enjoyed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
