Because blogging lets me be free. I get to explore the exhibitionist in me without the consequences. I get to tell my side of things, whether someone is listening or not.
Someone once said that blogging is akin to leaving your open diary on the kitchen table. I partially agree. But I think blogging uses a different language, a language that is more freeing, while writing in a diary is more formulaic -- we jot down what we did today or what occurred; it's more like a personal log book. But blogging is more introspective -- at least personal blogs are. It's not good enough to just say what we did, because the format of a blog draws out the impetus behind our actions, almost like how a therapist can extract the hidden depths we never knew we had.
And that's why I think blogging is more like a therapy session amongst our peers. People reach out to us; they empathize, sympathize, and criticize our situations, and we take from it what we will.
So I think blogging is more akin to sitting in an office of one too many therapists; some qualified; some inspiring; some malevolent; some stupid; some funny. We let them siphon the truth and the resolutions out of us.
Blogging is deeper.
And that's why I bother.
