@sabreW4K3 Plume doesn't appear to be active, unfortunately 🥺
There's a notice on the official Join Plume website saying the former developers don't have the time to maintain it anymore. Most of the former public instances now throw up errors of various kinds.
WriteFreely ( @writefreely ) is alive and well. I was seriously toying with the idea of setting up a blog through its main instance, which is called Write.as Professional. The sticking point for me was that the official on-platform monetisation tool (Coil) appears to be dead, and doesn't support members-only posts (like Ghost).
Ghost, when federation goes live, looks like it will be the best option for my blog.
WordPress plus @pfefferle 's plugins is another great option, depending on what you want to use it for. (There's no shortage of WP plugins!)
As for Lemmy, I could see a blogging-focussed front end being created for it, in the same way FediBB put a traditional message board front end on it, but one doesn't appear to exist at present.
