I prefer not to write about myself, but since (at least with a lot of my online writing) I write from personal experience (and sometimes research or reading I've done for "business-writing" writing purposes; I have to pretty much include myself/my own experiences into the thing because that's the point - that I'm writing from personal experience and/or other learning, but not from specific research done for a specific thing I'm writing.
(That's why so many of Hubs are kind of weird pieces of writing that don't particularly fit anywhere online. lol )
I do occasionally (not often) write something a personal story from real life, more just because I want to write it either to entertain some potential reader or else just to have it written down for my grown kids (like their arrival-into-my-life stories, that type of thing).
The subjects I tend to most want to write about are already covered by "authority sites", and I don't really think trying to regurgitate (in enough words) the best authority sites on HubPages is (again, with my subjects) is going to fly very well anyway.... which is why my subdomain is a mess as I try to figure out how, if at all, I can make my approach/subjects fit in on the site these days.
