Wow. This is even worse than I thought.
One great thing about Lojban is that it is supposed to be unique. What I read here is like if people said "Hey, I invented a Lojban-French", and "Me, a Lojban-Chinese", and "Lojban-English"... That sounds so stupid.
Let me be clear: I'm NOT judging anyone forking Lojban. Surely they had good reasons to do so. Actually nobody can pretend forseeing any case, and write an "immutable" language. So yes, it is obvious that the language evolves and will evolve, even an hypothetic "official an unique" Lojban.
What is unfortunate is that all forking work should be reintegrated in some way to the "trunk", or else we'll end up with many "Lojbans" wich will actually kill Lojban (whatever version).
I understand the lack of leadership, but it feels more like a lack of structures for democraty. It would be nice to have such structures, but unfortunately I don't know how this could be initiated. One idea would be to mimic software, a bit as OpenGL did, having the core, extensions, and proposals.
To be frank, I feel a bit betrayed. I feel bad because my hope was that Lojban was more that just an experiment. Someone, please, prove me it is...
