My keyboard journey was prompted by pain in my left wrist which I self-diagnosed as an RSI and prescribed a split-tented keyboard along with a course of vim-motions, twice daily, with meals. Both of these changes made a surprisingly significant impact to both my work ergonomics and speed!
I first purchased this Kinesis Freestyle 2 which was not bad, but it irked me endlessly that I could not map the CAPS LOCK key to ESC on the keyboard itself. And the Linux mapping was shaky at best.
Thinking that keyboards can't be that difficult to DIY, I stumbled on the Ergodox project which led to the Redox project, and the rest was history.
A friend of mine once remarked:
Don't you just hate it when you set out to solve a simple problem and end up in a community?
And don't worry, I won't become that guy that tells you how much your regular store-bought keyboard sucks. And I still use QWERTY because I don't believe in backwards-breaking changes to interfaces!
