Why's it gotta be about money? Sometimes it's interesting to follow what other people in the field are doing. I used to follow a ton of ML and compiler researchers on Twitter. Was a ton of interesting conversations around 2013-2015.
Few reasons:
1. I've gotten value from these folks on other platforms and mediums
2. I'm interested in what they have to share
3. I hope that starting to populate my following helps to choke out all of the bullshit brand recommendations I'm getting
Reason for sharing: can't imagine I'm the only one.
Not sure what you mean about the money thing. Whether you mean me or another person hypothetically following, I don't see a direct way to make money off of it.
