@mathias my 2 ₹
I just read articles, blogs (and Mastodon timelines!) ... almost exclusively. I have stumbled into and rejected several tangents as not leading to enough learning, and have ended up only looking at tools that complement work tech rather than "fix" work tech. Its just a little bit of #Prolog so far, with #TLAplus and #Erlang on the list next.
I think getting into the #RIIR sort of mentality doesn't help me at all. There is a lot to improve on "inside the box".
