He's right. Strengthening of real human presence against in the internet is a noble goal.
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.
This is a great perspective, and one that I've come around to after years of being anxious about being perceived online.
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.
For the more LLM-pilled would also recommend reading the Gwern piece on writing online: https://gwern.net/llm-writing
I would instantly lose my job if I did that.
Why would you lose your job for posting about and publishing your personal projects?
Conflict of interest and retaliation.
Just last week my friend told me a senior manager in a meeting made a passive aggressive comment about “I don’t know why the team is so busy and can’t take on more work right now, when they seem to have time working on other personal projects”. Referring directly to someone that was in their org who had just posted about some personal project work on LinkedIn.
It happens all the time…companies don’t like (or don’t approve) of work outside of work.
