This is the 3rd time I've seen someone mention they run their own instance. The other two specifically mentioned how it was for just them, and I'm wondering what the benefit is going that extra mile for just yourself. Is it worth it? Or is it simply a case of "because I fucking can?" 🤔
Does the instance itself hold a record or database of content posted, too? Like, could a personal instance be used to archive your own posts and comments, even if made on another instance through your personal one's account? That right there would be motivation to play with it for me. Well, that and the "because I can" thing.
As long as a user on your instance is subscribed to all the communities you comment on they should federate as far as I understand. Ask someone more knowledgeable before spinning one up though.
I run an open instance for everyone. The name (FOSSware) suggests that it's for people interested in FOSS (free and open source software) only, but in the description, I specifically mentioned that it's an open instance for everyone, just like with lemmy.world and other popular instances.
I'm running this instance, because I love technology and I'm hosting a lot of stuff for my family, friends and I, as well as some public facing things already. It's a hobby.
Another reason why I'm doing it is that I just want to give back to the community, as I strongly believe that decentralized tech is the future. We were proven time and time again that centralized approaches, where only one entity is in control, is really bad for the userbase.
