I feel like you post journals and yet they're hardly seen

It depends on the content of the journal. I've had some journals that gain dozens of comments, and some that get literally zero. As a watcher of your account, I often read your journals, but I might not comment unless (a) the journal topic is something I feel I can contribute a meaningful opinion on, or (b) the journal is directly asking for opinions/feedback regarding something.

Onto the main question, I honestly feel like seeing a bunch of text submitted as a screenshot or similar would just feel like spam on an art site like FA. What is it you hope to gain by posting a huge journal as an image submission? x]

I'm not exactly sure, I just feel like in some cases a journal despite whatever it's content are completely ignored and there has been times where I've posted a journal then years later I'd receive a comment

I'm probably just over thinking it

Oh I just thought of this other reason, in journals you can't put in measures to post to specific audiences, it's basically anyone in general.

A few swear words here and there and anyone could read them
