Indeed. This is, at best, scratching the surface. My aim was to create a list that ticked most of these boxes:
Alternatives to existing services - this is a question that comes up often so I thought there might as well be a list of the popular ones.
Relatively well developed and simple to use.
Has a user-friendly website that makes it easy for ordinary users to jump onboard (why Hubzilla didn’t make the list)
Granted, all of these list above is not straightforward to use, but can you add that on advanced category.
That’s where posts like yours come in useful - my list is just the easy on-ramp and then people can add in great resources like that which help people push on and do more. It’s kind of where I’ll be going next in my journey, so I am grateful for the post. If you, or anyone else, have more advanced services them keep them coming.
