Tinderbox
I had a nice long discussion with Michael Becker about setting up a blog and using Tinderbox for large projects. I was inspired watching Michael go deep into making Tinderbox dance. I've avoided making larger, all-encompassing documents with Tinderbox for fear of performance issues, but I'm not sure why. I don't think that's been a problem for years.
Seeing what Michael was doing has made me think about what it would look like to return to being all-in with Tinderbox. For years, every note I made started in Tinderbox. Once org-mode came along, Tinderbox was relegated to specific projects and my on-again, off-again Daybook. I miss it.
