I want Lemmy to succeed, but I'm highly skeptical of the ability of the instance operators to be able to do so. There's a great deal of technical sophistication that is required to support a large number of users, and from what I've seen, they don't have it. This isn't a slight against them in any way, but they freely admit that they lack SQL expertise, and I think I've seen some significant gaps in their knowledge on how to horizontally scale. This instance, for example, is all hosted on a single virtual server. There are no load balancers, no database sharding, no fanning out of services onto different servers...security is as well also likely in a shoddy state.
Again, no hate from me, nothing but praise so far. But there are some significant technological gaps here, and I worry their team isn't large or technically deep enough to fill them. What's in place at the moment is just waiting to tip over when any amount of traffic starts coming over. For what it's worth, I have offered my expertise to the admins around networking, security, scale, and automation.
That’s not how this works. Lemmy itself may be open source, but the instance it runs on is not. All the work in work in the world on the Lemmy codebase won’t mean anything if its actual deployment is not built for scale, and that’s not anything anyone but the admins can do anything about.
