Thanks so much for the thoughtful reply, Charles! I've been feeling like I should probably look into getting an alternative keyboard from the one on my macbook air. The pains aren't as bad as when I started, but I can't help but wonder about the benefit to some of the alternatives. I'm curious to look into that one you mentioned!

When you say compose at the keyboard, do you simply mean type? Most everything I've published to Medium was done with two fingers, and I certainly never had any trouble getting into a flow state and typing at a fairly decent speed. But it had begun to feel more and more restrictive. And I agree-- typically the mistakes I make are thoughtlessly confusing words that are phonetically similar or mixing "to" with "too" or "their" with "there."

Thanks for reading!
