> Engagement will always be better on new platforms

The primary effect is that communities with fewer users have stronger common bonds, the age of the platform isn't super relevant.

That said, the engagement on Twitter has been terrible since almost the very beginning. I'm sure it was super magical for folks who were at SXSW that first year, but the conversion rate has been garbage ever since then. Whereas maybe 50% - 70% of people will open the average cold email, the percentage of people who will click a link on Twitter was maybe 1 in 1,000 even 10+ years ago.
