I did. But never published anything publicly.
I already enjoy writing down my dreams and reading through them after months pass, they're written like i were describing them to a friend/stranger. That sorta kinda counts as blogging.
Another thing - last winter i started writing a summary for every week, what happened and how i felt. But i gave up on that idea way too fast Only 5-6 entries made.
Public blogging is another thing, i also considered it but never found anything interesting to blog about. I am also lazy.
