When I do/create something I find useful for others, I usually publish it on my website too. I (and probably almost every other developer/tinkerer) benefited from the open-source and the wealth of information available on the Internet so much, that giving some small part back is only fair.
Recently, I started using Marginalia Search as a first choice when researching something technical. Surprisingly, almost always I find a real person writing about their experiences, not some content farm or corporate bland talk.
The shift has been very rewarding and has opened up tons of opportunities and partnerships both personally and for my startup.
The snark:signal ratio section rings very true.
