Semi-public
Something about hyper-logging (capturing your mind in prose) feels desacralized when I see it as the grown-up development/extension of my AIM bio, or my original Facebook bio (which had a whole series of categories, like favorite movies, books, etc.). Why keep an extremely detailed and public log of my self and thoughts? I guess I see it like a change log of my evolving identity. That was sort of Montaigne's whole thing (perpetually in transit). I imagine the norm is to burrow into your shell of self for as long as possible, to avoid the confusion of drift, but I try to harbor a non-static self. I feel a cringe in sharing this self-congratulations. There's the tension.
I think I'm doing an irregular thing by obsessively documenting thoughts, and from my own perspective it does feel like I'm continuously evolving, but an outer perspective might see this as nothing more than a frivolous blog. It's likely that my whole arc is illegible. Some degree of it comes to surface, like my ever-shifting "career," but most of how any of us feel, think, and change is illegible to each other, except in extreme rare cases of friendship, and so the more idiosyncratic your path, the less anyone can understand you.
I suppose my logs could function as a private journal, but it would lose an important quality. While, there are some consequences of writing in public (a subtle self-censorship), there's something more important you gain: the stakes of knowing that your work could be read in the future, if not by a friend or stranger, then at least a future version of yourself. Whoever it is, if they care to spend the time to read, they would understand you more than probably anyone in your life. That slight pressure snaps me into a mode where I try to be coherent, articulate, and sometimes expressive. When I look back at my old chicken scratch journals, I almost always skim and skip and hate it. But when there's a slight care in crafting the language of my thoughts, it becomes something that outlives the moment.
And so if public writing comes with self-censorship, and private writing comes with a lack of stakes, then the way to go is semi-public publishing. It gives you both freedom and stakes. You won't grow your audience this way, but I think you will forge a sense of self and voice that you can bring with you when you try to build an audience, but that's really secondary. It's the self and voice that matters.
