I'd love to talk to some of you privately, but you have no way for me to contact you. Many more lurkers can relate. If you feel like you'd enjoy a conversation with a stranger, you should probably add something.
Agreed, I've had great interactions with folks from HN. If people have a website/blog, I recommend including a link in the bio. It's a great way to discover new stuff and for others to discover yours.
Or is it rather that you want direct access to high-value individuals and experts?
Personally, I can see many more downsides to having scrapable contact info:
- crypto-peddling
- soliciting for jobs and investments
- social engineering attacks
- de-platforming for "politically incorrect" statements made 5 years ago
