Ergonomic, split and other weird keyboards
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Ha, kinda the same story for me.
For my first ergo split, I wanted to build a Corne, but ended up building a Lily due to not being able to order the Corne and being somewhat uncertain of "just 3 rows". Now my mapping has gravitated to something that'd fit on a Corne, I don't use the outermost thumbs and am weaning myself off of the num row. Still considering whether I should try and work with 5 columns instead of 6, but there's some useful keys there — for now.
I can see myself building another split in the future (something that's slightly more travel-friendly than the Lily), and it's probably going to be a Corne. The Lily's thumb cluster is slightly to far to the outer edge for my comfort.
