The basic premise of Indieweb is that you tend to deal in public content, public discourse. But I only do that on Twitter and Mastodon, really. On social networks which permit it, like G+ and the Unnameable One, I like my privacy.
Even on Twitter and Mastodon, I don’t try to get “famous” or get a lot of likes or reshares from strangers or anything, I just would rather talk to a few interesting people.
Maybe Indieweb can enable that thru the communication features….
