For me it is partially that for sure. There's plenty of stuff I would - in theory - not mind to post publicly. E.g. my personal notes about interesting stuff I stumble on, want to read up on, how to troubleshoot stuff etc. But the issue is a) I don't feel like investing the time to individually post only subsets and b) posting all of it makes me feel way too vulnerable. At a quick glance suddenly everyone would just know all my interests, my expertise and lack thereof in areas and so on. Just not worth it in the current internet and societal discourse.
