This is an ongoing question for me, too. I'm far more forthcoming about my issues now that I'm older and more inclined to post about them because I recognize that my experience can be helpful simply by virtue of naming it. Plus the older I get the more I realize that my issues aren't really mine at all, kind of a generic human ownership. For me times not to post are when wounds feel too tender to share, or when I'm in the middle of the process, or when seeds need more of the nourishing darkness to grow a bit before being exposed to the light of the manifest.
Your plan for a handwritten shadow journal combined with online general work sounds like just the right balance.
You expressed this so beautifully! And your words have reinforced my decision, because I am definitely in a place of tender wounds and seeds in need of nourishing darkness.
My Oracle of Shadows doesn't come with any recommended spreads, so I made one up and posted the results in the Oracle Readings thread. Ironically, it ended up being a bit of general shadow work.
