You make a good points. I guess I'll just have to wait and see what happens. But hey, my old Twitter account had no followers, no comments, no likes, and my follow list was private, yet, I still got spammed with DMs and notifications of scammers tagging me.

Personally, I don't bother with the global feed. I'm only interested in the posts from people I follow and the topics/tags that i care about.

Free relays not keeping notes in storage forever is a good thing, some folks might not want their posts hanging around online indefinitely.
