And they don't now. Which is why it's useful to be on platforms that people do use.

The point f6v was making (I think) was that the same argument above, against using something else, was used by the email users of the day ("everybody is using email, why should I use ICQ or MSN etc."). But then eventually the tide changes. It's just difficult and lonely to be the first :)

People used to send writing on paper in an envelope. Some still do. Perhaps one thing that’s not being said is the degree we each care about communication relative to how we communicate; this is a very personal topic. I am one who deleted all social media (except HN; joined recently because the stress of it is lower and I still like to share) and one who is comfortable with the slow pace of letters and email-as-letters. I’m of the Star Wars generation, growing up with computers and still knowing what is was like to place orders by calling on a rotary phone the number on the back of the catalog.
