For me, extended periods of "therapeutic refactoring"
Perhaps with the added freedom to work on features or bug fixes that come up as I discover them. Lots of the best parts of the DEV codebase I've contributed were in these periods.
I think this would be mine too, but in a different way. Our copy has been written and rewritten by many different people in many different countries over many different years without any style guide, and I'd love to develop a style guide and get all copy up to a consistent standard!
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
