Blogging: Acceptable tell-alls?

It occurred to me earlier today that blogging is really a modern and public way for anyone to instantly publish a tell-all book, the kind of publication that can cause quite the stir in Hollywood and other social circles.

My questions of you, dear readers, are these:

*even if you carefully change names to 'protect the innocent' or not so innocent, depending on the experiences, are there lines you should be careful not to cross?

*What if, for you, writing about the experiences is like a form of purging, a confession that you really need to get out of your system so you can gain closure and move on?

*Does it matter if what you need to get out in the open involves people that are no longer in your life? Does it matter what you write then?


I'd greatly appreciate any input you have to give, this involves personal things for me, things I need to expel and gain closure on.. I just want to find the 'right' or at least best way of doing so. And that's where I turn to you, dear reader. Any opinions and ideas you have would be awesome!
