In which I contemplate exploiting everyone I know for a few cheap laughs

I've been trying to keep this blog fairly non-personal. As I've noted before, nobody gives a fuck how my day way, and as I'm trying to be entertaining and lighthearted, talking about things that are close to me just don't fit the format. Still, this blog is meant to be a practice area for me to strengthen my writing. Given that, I do feel I should be trying to get some resembling insight into the human condition down.
A few things have happened to me recently, that I'm going to try and keep as vague as humanly possible. I do feel that these events have changed my views on life, especially relationships (not necessarily romantic, but how we as people relate to each other). But if I had written about them, the people involved probably would have instantly recognized themselves, and might very well have kicked the living crap out of me. So my question is; should the personal become the public if there is value in it being analyzed? At what point can I justify cannibalizing my life and the people in it, to entertain?
I think this is the ultimate paradox at the center of all art. Great art has traces of those who created it inside: from the director and writer of a movie leaving hints of autobiography and personal philosophy to the author who lives his fantasy life through his novels, art is nothing more than the artists mind, filtered to become universal. But how diluted can those emotions and thoughts get before they become trite, too specific to be traced to a specific thought pattern that makes up the artists soul? But at the same time, if they don't filter at all, especially if their art deals openly with relationships, or is heavily autobiographical in nature, is it fair to exploit those in their close circle? How do you justify selling your closest friendships and romances to a general public?
So I'm struggling with that. I want to put something valuable and true and genuine out, but I don't want to hurt those who give my life meaning, even if it means giving my art meaning. But there's no easy way to avoid that.
