@grafo It's such a killer feature! I'm somebody who tends to want to see a wide variety of content, so while the upside of being on a smaller instance is a good local community, one of the downsides is the Federated timeline is kinda small and not always representative of my interests.... I have an account on a much larger server, but on there, the Federated timeline is way too much. Being able to follow local timelines of other instances is *so* helpful in being to find other folks who are talking about stuff I'm interested in.
The only thing I'm finding to be a drawback with #Fedilab is it seems that I can only have one account linked to it... so if I want to reply to something with my other account I have to go use the web app... but other than that, it's great!
