I rarely write any code outside of work, to be honest, except for simple CS algorithms, just to keep in touch with the basics some companies ask on interviews: sortings, data structures, that sort of thing. But that's mostly because my life is already mostly occupied by work / programming as it is.
Talking? Sure, but in my experience even among fellow developers it's sometimes hard to find a topic interesting for both parties. Even among my colleagues some are not really interested in things like SOLID, clean code, functional programming and tend to focus on frameworks and other aspects of the craft.
