Some clients (at least Connect and Voyager on Android) have a user tagging feature, so I've been tagging people I see over and over or trolls, or whatever. It's really handy to start to easily see who's around and posting.
Honestly, it depends on your circles and network. I only remember seeing The Picard Maneuver maybe twice, didn't know of them before this week. I've seen your username far more, for example.
True true. I think Lemmy.ml tends to be more insular than most instances though? e.g. the default sort is Local rather than All. Like basically for people who already had most of their Fediverse needs met, there was less need to join communities across the wider range?
I don't know enough to say if it's more insular or not, I don't know how common it is to have the default sort as All, but we're definitely worldly enough for other instances to have some users pushing stereotypes on us when we comment.
You do have some point about lemmy.ml having enough instances that you can get by with Local as default, but I assume most people would be subscribing to or exploring other instances too? I really don't know.
