Im definitely in that boat. Tying back to the baseball example I searched for communities with the keyword baseball and subbed to the largest. With some other interests I have actually joined multiple of the same communities that are just in different lemmy servers.
I kinda get this. It’s not reddit that I need, I just need aggregated links of shit I’m interested in. A “front page” to my internet, so to speak. There are plenty of the smaller communities that don’t yet have much presence here, so I feel a little itch occasionally, but hopefully they’ll start to develop too.
As long as this place continues to grow, it could be really easy to just abandon that old site. I’m trying to contribute and help that process.
