Huh. Are you using the web browser or an app? Oddly, when I browse my gram.social home feed via the web browser, it’s mostly (but not exclusively) just the default accounts in my feed, but when I browse via the Pixelfed, PixelDroid, or Pixelix apps, I’m seeing lots of posts coming from many other servers, including Mastodon servers.

Which server did you join? I’ve been following lots of hashtags (including cats), so my feed there is pretty active. Just hoping some IRL friends and family will join soon so I have those sort of accounts to follow and share with.
